dnsmasq use different upstream servers for specific hosts by IP

Question

I am trying to set up the following scenario:

Local raspberry (192.168.0.9) is used as both dhcp server (dhcpd) and dns server (dnsmasq).

I have two sets of devices (my own and everyone else's), that receive their IP addresses from specific ranges and DNS Servers specified in dhcpd.conf as this:

subnet 192.168.0.0 netmask 255.255.255.0 {
    option routers 192.168.0.1;

    pool {
            deny unknown-clients;
            range 192.168.0.20 192.168.0.40;
            option domain-name-servers 192.168.0.9;

            host A {
                    hardware ethernet 11:22:33:44:55:66;
                    fixed-address 192.168.0.21;
            }
            host B {
                    hardware ethernet 66:55:44:33:22:11;
                    fixed-address 192.168.0.22;
            }
    pool {
            range 192.168.0.2 192.168.0.19;
            allow unknown-clients;
            deny known-clients;
            option domain-name-servers 8.8.8.8;
    }
}

That works fine. I have my own devices use dnsmasq for specific rules, ad-blocking and so on, while other clients use google's dns without restrictions.

However, I would like to

have IP assignment done via dhcpd pools, but
use dnsmasq as dns server for both IP address ranges
provide every client that connects with some locally defined name resolution provided by dnsmasq entries (like 'address=/homenet_files/192.168.0.9')
use different upstream servers for the different IP ranges in dnsmasq

example: client in IP range 192.168.0.20 - 40 should use opendns server=208.67.222.222 , others server=8.8.8.8

Is there a way to provide different configuration files for specified IP ranges? tbh the dnsmasq manual is over my head regarding this question. Any help appreciated.
