Yeah, that’s what happens when you work with a gazillion of tracks, routings, and most importantly group tracks.
Having the same problem here.
But when we move such a project to a more powerfull computer, the annoyance gets less.
We have the possiblity to use an insane amount of tracks and grouping, and that is what we do.
Without ever wondering what we ask from the soft/hardware …
