I also know it from CC PP. There it also works the following way. 
Probably you mean that.

Since I am used to it from PP as well, it would surely be a significant 
improvement. The Group feature is relatively fresh, as Cinelerra lagged 
behind the other NLE's as far as the timeline feature was concerned. GG 
did an excellent job and improved many things in the timeline. I don't 
know if he could add this feature.  In the long run I would welcome it 
and join this feature request because it is a very big relief. In PP it 
greatly facilitates the work.
