Changing dynamic during arpeggiation

Your idea

I propose to expand the notation options (currently available in Musescore) of dynamic notation to include arpeggiation.
It would be great if the user could place the hairpins vertically right in front of the arpeggio sign, thereby indicating how the loudness should change during the playback of the arpeggiated chord.

Problem to be solved

This will allow the reader/performer to clearly understand exactly how the arpeggiated chord should be played. And it will be easier for the user to compose such a musical notation, instead of entering a bunch of notes before the beat and indicating the dynamics. I suggest a simpler and more understandable version of the notation.

No response

Additional context

It should be understood that the change in dynamics during arpeggiation occurs taking into account the fact that the chord is played before the beat (and the last note falls on the beat), which has not yet been fixed in Musescore, as I outlined in issue #22342.

No implementation files or tests are identified. Start by reviewing the existing dynamic and arpeggio behavior, then read issue #22342 for the timing constraint; done means supporting vertically placed hairpins that convey dynamics during arpeggiation in notation and playback.
