It is a well-kown challenge, but:
The record will not matter/be possible in ton of cases as soon as you need to make some more rapid frame precise assignments.
Even more if it needs to be on certain lems or in different parts of the map
If they need to be on consecutive frames I doubt even hotkeys could do it.
It is not possible to determine before investing tons of time if the record is even possible on a level and I think general icons should be applicable for
all levels and not just for an undetermined subgroup.
Do we really need an extra icon here especially if not every level allows for this challenge?
