would copying and pasting the stomps block and the effects block to all of the slots in a performance do what you need?
No. The idea is to have it locked so I can go from slot 1 to slot 2 without the on/off state of any stomps or effects changing but then be able to switch to a new performance that has its own stomps and effects. Leaving them unlocked would make the former impossible. Locking would make the latter impossible.
