Key frame edit start-pause batch separator/grouping

While key frame edit is really nice and works pretty great.

Not sure if previously been suggested or such feature exist?
Since selecting shows frames containing points. Can then manually browse frames and navigate to identify frames from same scan batch, but it’s sometimes only good guessing. Like when looking for misaligned or bad frames.

Some kind of simple separator/ timestamp/grouping between scan pause/start batch would be great. Maybe also selecting all particular batch of frames?
