Copy and paste discrete notes with their rhythmic pattern

Problem to be solved

Say I want to make the left picture into the right one:

The most straightforward way coming to my mind is to selecting all these low A's then cut and paste, sadly it doesn't work, I have to copy-paste the whole bar and delete useless chords one by one.

Due to things like issue #19045, when writing for piano I sometimes prefer to work in a single staff at first and split it some way afterwards, but not able to copy & paste discretely selected notes like that make it much slower; and lacking box selection ability (#15282) makes the last step of deletion even harder to complete.

There's an action called 'move selected note/rest to staff above/below' but it's for cross-staff beams...

Prior art

In a DAW I can simply copy and paste any selected notes in any topology shape, and their duration relative position will be kept. Not strictly a prior art from notation software tho.

Additional context

Tried this on MS 3.x and it doens't work either.
