Is it possible to set/lookup Ansible facts when play returns multiple values

Question

I have the following playbook in AWX that looks up Infoblox hosts based on their Mac Address and then outputs the information in a more user friendly format.

The current playbook works providing that a single host with that Mac address exists but fails if there are multiple.

---
- hosts: localhost
  connection: local

  vars:
    niosip: ""
    niosmac: ""
    niosdhcp: ""
    nioshostname: ""
    niossearchcatagory: "{{ 'name' if searchcatagory == 'Hostname' else 'ipv4addr' if searchcatagory == 'IP Address' else 'mac' if searchcatagory == 'Mac Address'}}"

  pre_tasks:
    - include_vars: 
        file: creds.yml

  tasks:
    - name: fetch host record
      set_fact:
        host: "{{ lookup('nios', 'record:host', filter={niossearchcatagory: searchcriteria, 'view': 'Internal'}, provider=nios_provider) }}"        

    - name: Set niosip
      set_fact:
        niosip: "{{ host.ipv4addrs[0].ipv4addr }}"
        nioshostname: "{{ host.name }}"
        niosdhcp: "{{ host.ipv4addrs[0].configure_for_dhcp }}"
        niosmac: "{{ host.ipv4addrs[0].mac }}"
      when: host != [] and host.ipv4addrs[0].mac is defined

    - name: Set niosip
      set_fact:
        niosip: "{{ host.ipv4addrs[0].ipv4addr }}"
        nioshostname: "{{ host.name }}"
        niosdhcp: "{{ host.ipv4addrs[0].configure_for_dhcp }}"
      when: host != [] and host.ipv4addrs[0].mac is undefined

    - name: Host not found
      debug:
        msg: 'Cant find related host'
      when: host == []

    - name: Display Display Registration Info
      debug:
        msg:
        - Hostname = {{ nioshostname }}
        - IP = {{ niosip }}
        - Mac Address {{ niosmac }}
        - Registered for DHCP = {{ niosdhcp }}
      when: host != [] and host.ipv4addrs[0].mac is defined

Variables niossearchcatagory and searchcriteria are passed into the playbook via an AWX Survey.

I've searched possible options around using loops or splitting the output down but I'm really at a loss on the best way to process this.

If the output matches this then the playbook works as expected

{
    "changed": false,
    "ansible_facts": {
        "host": [
            {
                "_ref": "record:host/ZG5zLmhvc3QkLl9kZWZhdWx0LnVrLmFjLmJoYW0udGVzdC5zbmF0LWF3eHRlc3Q1:snat-awxtest5.test.com/Internal",
                "ipv4addrs": [
                    {
                        "_ref": "record:host_ipv4addr/ZG5zLmhvc3RfYWRkcmVzcyQuX2RlZmF1bHQudWsuYWMuYmhhbS50ZXN0LnNuYXQtYXd4dGVzdDUuMTQ3LjE4OC4zMS40Lg:192.168.31.4/snat-awxtest5.test.com/Internal",
                        "configure_for_dhcp": false,
                        "host": "snat-awxtest5.test.com",
                        "ipv4addr": "192.168.31.4",
                        "mac": "10:20:30:40:50:60"
                    }
                ],
                "name": "snat-awxtest5.test.com",
                "view": "Internal"
            },
        ]
    },
    "_ansible_no_log": false
}

And here's an example of the play returning multiple values

{
    "changed": false,
    "ansible_facts": {
        "host": [
            {
                "_ref": "record:host/ZG5zLmhvc3QkLl9kZWZhdWx0LnVrLmFjLmJoYW0udGVzdC5zbmF0LWF3eHRlc3Q1:snat-awxtest5.test.com/Internal",
                "ipv4addrs": [
                    {
                        "_ref": "record:host_ipv4addr/ZG5zLmhvc3RfYWRkcmVzcyQuX2RlZmF1bHQudWsuYWMuYmhhbS50ZXN0LnNuYXQtYXd4dGVzdDUuMTQ3LjE4OC4zMS40Lg:192.168.31.4/snat-awxtest5.test.com/Internal",
                        "configure_for_dhcp": false,
                        "host": "snat-awxtest5.test.com",
                        "ipv4addr": "192.168.31.4",
                        "mac": "10:20:30:40:50:60"
                    }
                ],
                "name": "snat-awxtest5.test.com",
                "view": "Internal"
            },
            {
                "_ref": "record:host/ZG5zLmhvc3QkLl9kZWZhdWx0LnVrLmFjLmJoYW0udGVzdC5zbmF0LW15d2Vi:snat-myweb.test.com/Internal",
                "ipv4addrs": [
                    {
                        "_ref": "record:host_ipv4addr/ZG5zLmhvc3RfYWRkcmVzcyQuX2RlZmF1bHQudWsuYWMuYmhhbS50ZXN0LnNuYXQtbXl3ZWIuMTQ3LjE4OC4zMS4yLg:192.168.31.2/snat-myweb.test.com/Internal",
                        "configure_for_dhcp": false,
                        "host": "snat-myweb.test.com",
                        "ipv4addr": "192.168.31.2",
                        "mac": "10:20:30:40:50:60"
                    }
                ],
                "name": "snat-myweb.test.com",
                "view": "Internal"
            },
            {
                "_ref": "record:host/ZG5zLmhvc3QkLl9kZWZhdWx0LnVrLmFjLmJoYW0udGVzdC5zbmF0LXdlYg:snat-web.test.com/Internal",
                "ipv4addrs": [
                    {
                        "_ref": "record:host_ipv4addr/ZG5zLmhvc3RfYWRkcmVzcyQuX2RlZmF1bHQudWsuYWMuYmhhbS50ZXN0LnNuYXQtd2ViLjE0Ny4xODguMzEuMy4:192.168.31.3/snat-web.test.com/Internal",
                        "configure_for_dhcp": false,
                        "host": "snat-web.test.com",
                        "ipv4addr": "192.168.31.3",
                        "mac": "10:20:30:40:50:60"
                    }
                ],
                "name": "snat-web.test.com",
                "view": "Internal"
            }
        ]
    },
    "_ansible_no_log": false
}

And this results in an error as the variables host.name, host.ipv4addrs etc.. don't exist which I presume is becasue there are multiples.

Any help on how to output each registration would be gratefully received.
