Track Divide Button to Delink Top and Bottom Time Line

I would absolutely love if there were a button added to the track divide window that allowed for separate zoom settings for the timeline for the track divide portion. This would make for a closer to 3 point editing workflow for me.
As it stands now when I do classical style edits I am constently zooming in and out and it makes it very difficult on long timelines to grab small edits and throw them onto a track at the very end of a 20+ minute segment when grabbing a half a second clip. Pryamix does this so well but I really enjoy working in Nuendo and Cubase overall and prefer to stay on OS X as much as possible.
