filter notes in beamgroups

Would it be possibles to get something like ‘filter first or last notes in beam groups’ similar to filter notes in chords? I do find myself often selecting all the first notes of beam groups to add an accent or so. Or - in groups of three notes - the first two are slurred and the last two get a staccato dot.
It would be nice if you could add these articulations for longer passages in one stroke.

This is a nice idea that I don’t think has been suggested before. I’ll make a note of it.
