1) In EuControl --> Assign
There you can assign any track of your project to a fader.
2) Then you go to Layout and save it (you must also save your project after changes).
repeat, make all necessary Layout.
3) Then also in EuControl add to a softkey or to the transport Keypad a command --> MC --> Recall Layout. I use the Keypad, this way with the keypad numbers 1-9 I can recall plenty of faders layouts and do not need to use the bank buttons.
You can even program them on the touchscreen.
