Two active modes simoultaneously

Hi, I am just getting started with CSS and I am trying to create a script for my Novation Launch Control XL.
I really like the original Ableton Script and just want to improve upon that (for my workflow).

In the original Script, you can change what the knobs control and what the buttons control independently.
I tried to recreate that with different modes (Knob mode 1 + Knob mode 2 + …)(Button mode 1 + Button mode 2 + …), but I am guessing, that only one mode can be active at a time.

Is there another way to achieve that functionality?

And is there no way to have buttons always have a certain functionality, no matter what mode the controller is in? I read about mode 0, but I can’t assign controls to it.

Thanks in advance
