Change multiple clips duration and move clips in the timeline at the same time


I would like to select all clips in the timeline (CTRL+A) and then cut off 4 frames from the end (edit duration). At the same time all clips should be moved to avoid getting 4 frames of no video between the clips.

I can't find such tools in kdenlive but maybe there are tools to accomplish this already in place?

If I would create such function, where would the best place to put it be within kdenlive?

Maybe would it be to adjust the "Timeline / Current clip / Edit Duration" function to be able to cut some frames from the end of multiple selected clips (Crop end)?

Or do you have another suggestion that's more logical?
