deactive notes with fold ableton push 2

[sirianth]

(1.) There appears to be a way to deactivate notes on the push by muting e.g. certain drum sounds.
However, (2.) there doesn't appear to be a way to "fold" the representation of used drum sounds on the push; is that correct?
I use massive drum racks completely full, hunting down what I want to hunt down to mute for a performance is a terrible chore, and won't work in a live setting... (3.) When I'm on my monitor with the mouse I can fold and deactivate and reactivate, which is the exact effect I want, but I'd like to do in on push.

There's not really a way to do it from Push, but if you use the Melodic Step Sequencer layout you'll get something similar.
