Is it possible to bind a workspace from within a Pipeline (and not a PipelineRun) or create a PipelineRun with bound workspaces using GUI?

Question

I'd like to be able to start my pipeline which uses two workspaces using the Tekton dashboard (GUI) but from what I can see, there is no option to provide workspaces here.

The only two options of creating a PipelineRun with bound workspaces I can think of are to either:

• Create it programmatically and apply using either kubectl or tekton-cli
• Create a TriggerTemplate with bound workspaces and run the pipeline by a webhook to an EventListener

My main problem is both of those options require the developer to go through a very non-user-friendly process. Ideally, I'd like to run the pipelines with bound workspaces from tekton GUI. Can this be somehow achieved? I've tried providing the binding in the workspaces section of the Pipeline definition as below:

  workspaces:
    - name: source-dir
      persistentVolumeClaim:
        claimName: gradle-cache-pvc
    - name: ssh-creds
      secret:
        secretName: ssh-key-secret
