Is it possible to schedule a workflow with a variable or dynamic value? I’d like to be able to set the cron for a workflow via a rest api call.

I imagine using something like the following:

on:
  schedule:
    - cron: ${{ github.event.inputs.cron }}

But of course there’s no event to provide inputs in this example. I thought maybe I could use env context instead, but according to the docs:

You can only use the env context in the value of the with and name keys, or in a step’s if conditional.

If you have any thoughts on setting a scheduled workflow via a rest api call, I’d love to hear them.
