Mouse Split (scissors) in Lower Wave Editor

Why there is no mouse Split (scissors) functionality in lower wave editor ?
Spliting at cursor works, Splitting Loop works, so why I cant just split wave clip
just by click on nedded position.
(just for sure: Select region in lower edit and delete that region, is not split audio which I’m looking for)

Reason why to do precise wave editing in Lower edior and not on timeline is better, (pre-set) wave display and zoom, while keeping overview on timeline.
