Per-schedule parameters for worker-based deployment schedules

First check

• [X] I used the GitHub search to find a similar request and didn't find it.
• [X] I searched the Prefect documentation for this feature.

Prefect Version

2.x

Describe the current behavior

We're using worker-based deployments. AFAICT from https://docs.prefect.io/latest/concepts/schedules/ and https://docs.prefect.io/latest/concepts/deployments/, parameters can only be set for a deployment as a whole. I suppose this is moot given this caveat:

Support for multiple schedules in flow.serve, flow.deploy, serve, and worker-based deployments with prefect deploy will arrive soon.

Describe the proposed behavior

If/when support for multiple schedules arrives, we'd like to have different schedules each with its own set of parameters in a given deployment.

Example Use

Our current use case would be a clean-up flow which is parametrized over services, and we'd like to have a single deployment scheduling the clean-up for a bunch of them, but via custom schedules for each service to avoid cluttering up the deployments list.

Additional context

Apparently this used to be possible for Prefect v1, if I read this discussion right: https://github.com/PrefectHQ/prefect/discussions/4543.

Big +1 from us for this idea. We used it quite a bit in V1 and it would be very useful for selectively running certain DBT models on a schedule

I'm also looking for a way to have one deployment with multiple schedules, and each schedule has different parameter values.

My use case is for ML pipelines.

Same here, definitely something we'd be interested in!

Much needed feature! Is there any simpler workaround for this, besides deploying multiple flows or handling array of inputs into a single deployment?

[delkirksey]

+1 here! Would be an extremely useful feature.
