Default values for workflow dispatch inputs from URL

Hi,
I would like to auto-populate the defaults for the inputs to a workflow_dispatch run based on URL parameters. So for example, if the url was something like github.com/example/example/workflows/example.yaml?input.abc=value

then the text field corresponding to the “abc” input would be prepopulated with “value”.

I didn’t see this in the documentation, but it’s possible I’m missing something. Is this doable? If not, consider it an obvious feature request.
