Mixer Zone Split Scrolling

It would be awesome if, in the mixer, There would be an adjustable split and individual scrollbars for left and right mixer zones.
I use the zone function for keeping all of my Buses / Group / FX channels on the right, and the more Groups / FX channels etc. you get, the more space the right zone will take up, which decreases the size and thereby overview of the left zone. Hope this makes sense. To be clear, I’m talking about the channel zones, not the workspace zones.
