Yeah I could see why you’d do it this way but as a workflow it’s not really the norm. If you *had* to do it this way- use a disabled clip instead of gap. That way your markers will be preserved but functionally it’s going to look the same as the gap you’re doing.
Also I think it would make way more sense to nest these compositions into Compound Clips instead of trying to force things into place with gaps all over the place.
