Ignore grouped tracks in the numbering

Hello,

I’m completely new to CSS, but so far I’ve mapped everything the way it works for me. But there is one thing I can’t get right, I’ve searched a lot:

Is there a way to ignore the groupped tracks in the track numbering?

I have programmed the 8 faders from my controller to the volume faders of the first 8 tracks in the red box, but I want that, if there is a group, only the group is counted and not the sub-tracks also occupy faders from the controller. Surely there is a solution for this? Thank you very much!
