What I would love to be able to do:
1 - Save an effect as a favorite.
2 - Use that effect in multiple patches, inc snapshots
3 - Decide that I want to edit the effect, do it while in in a patch
4 - Re-save the favorite over the top and have it update everywhere else that favorite is used.
I know I can do 1, 2 and 3 it's part 4 that I don't think is possible.
If you know differently then please share it will save me a ton of time.
