Novation LaunchControl 3 (Midi remote)

I just bought a Novation launch control 3.

I would like to use it as:

8 upper encoders: to control the 8 sends of the selected track

8 lower encoders: 1 for the Pre Gain of the selected track and another, for example for the volume of the Room control. (the others without assignment

the bottom 8 buttons: to Shut Down, turn on the selected track sends.

Note, I would like to use or create my own script, without installing the novation one

is this viable in Cubase 15?

use case, create a track, and add 8 sends to it, being able to start controlling it immediately, without having to change any option in Launchcontrol.
it’s possible?

thanks
