Kp3+ editor external control modus

hi guys, have a bunch of kp3+ here. last day for first time i tried to use external control modus. with the kp3+ editor its not so hard to change the cc values been send. cant find a manual of the editor nowhere. my question: if i am in external control modus (shift + button 8) i can dial with the programm knob different pages named p.001, p.002 and so on. i thought this are all different programms where i can assign different midi ccs. but in the editor i dont find a way to arrive those differnt layers. any of you can give me advice how to do this? thanks and have a nice day.

by the way controlling the octatracks parameters with the x/y pad of the pk3+ is really funny…
