Go to last used bank

I need some tip for the "go to last used bank" option.

I have created a MC6 bank to control the looper of my Echosystem.

From any other bank of the MC6, I have set a long press on A to access

this looper bank, and this works fine.

I'd like then to return to the last used bank with another long press in

the looper bank.

However, when ticking the "go to last used bank" option with the "set bank"

type, this still moves to the bank given by "bank number", not the previous one.

Thanks for the help!
