I’m not shure if I understood your problem in the right way.
But if I understood it right, the solution for you is working with “parts”.
You have four of them for each bank. So lets say you are playing a pattern. All tracks are in C may. This is saved to “Part 1”. Now you change every trach to D min. This is saved to “Part 2”. Now you only have to change the parts and all tracks jump from C may to D min and back.
