Thanks, this seems a great idea, to automatically put the flow in place.

Question: is there ever a scenario where a user may need, or want, to
override the automatic choice made here? Or is it just the case that once
the flow is installed, it works the same whatever group it's added into?
I would assume the latter, but just want to confirm.
