hey there, a few questions regarding <https://docs-2.prefect.io/latest/concepts/results/?h=persist#result-storage-location|result storage> (in prefect 2):

:one:  can I use the `prefect.runtime` context with `result_storage`? i.e.
```result_storage=S3Bucket(
  bucket_name="foo_bucket",
  bucket_folder="state/{flow_run.flow_name}"
)```
:two:  is there a way of setting `result_storage_key` more globally, e.g. through a ENVIRONMENT var?

Hi Constantino, I don't think you'll run into issues with using the runtime context in result storage. If you're looking to get the flow name from `flow_run`, I believe it will look like this:
`runtime.flow_run.flow_name`

I don't think there's an environment variable that sets the `result_storage_key` globally.
The closest thing I've found is:
`prefect config set PREFECT_DEFAULT_RESULT_STORAGE_BLOCK`,
which sets the default storage location for your workflow, but you'd still need to set the `result_storage_key` at the task level.

IMO I think it's worth exploring adding an environment variable to achieve this. Mind creating an idea in the <https://github.com/PrefectHQ/prefect/discussions/categories/ideas|GitHub discussions>? I can start one next week, unless you get to it before me.
