Agreed this would be a wonderful feature. +1
Cubase does NOT have a truly comparable edit mode (especially multi-track), and could surely stand to benefit from it.
I use the feature in Reaper frequently for complex multi-track dialog editing, and the workflow is extremely fast – much faster than in Cubase. Reaper’s implementation of it is outstanding, and it’s been that way for many years. I have requested this feature for Cubase years ago, but gave up waiting for it.
But I’m happy to cast a +1 vote. Maybe Steinberg will do it this time.
