is there a way of setting result_storage_key more globally, e.g. through a ENVIRONMENT var? as opposed to defining it on each task?

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.

Given that result_storage_key can use the prefect context, it would be great to be able to set it to a value like "{flow_run.flow_name}/{flow_run.name}/state.json" for ALL tasks at once through an ENV.

Hey @ConstantinoSchillebeeckx! I think this suggestion makes a lot of sense! Would you be willing to submit a PR to add a setting for a default result storage key? We've been reworking the Prefect settings recently so I think it'd make sense to include this setting in the TaskSettings model.

sure thing, I'll take a look this week.
