Break multi-bar rests in all parts

A time saving idea:

It would be nice to be able to right-click on a bar line in the score or a part and select ‘break multi-measure rests in all parts’ (split into two sets of multi-measure rests).

I often decide that these need splitting whilst in a part. It could maybe be achieved with a ‘splitting’ normal barline.

I think this is what happens if you insert a normal barline, or am I missing something?
