Upper/Lower zone for tracks in project window

Would like a system to pin track/s on project window in place when scrolling up/down, or at least make like in the mixer to pin it to up or lower zone.
i think it would be helpful when editing when u want some tracks to be always there (i know about the “divide track list” option but its not the same)

So, you would like a setting to make the selected track not disappear from the view when scrolling down. Am I close?

yes, not selected per say, but tracks that has a function activated to pin in place or like the left/right zone in the mixer, so when you scrolling those tracks stay at view and dont scroll
