Adding options for the harp glissando

Your idea

I propose to improve the existing notation for the harp glissando by adding the ability for users to choose the following type of notation:

Problem to be solved

This will allow performers (or just readers) to better perceive in which scale the glissando should sound (rather than peering into the pedal tuning scheme in order to determine this).
Now about the next problem. Recently, I had the need to mark the glissando one rest after the bar-line. I got the desired look, but not the sound, because there is a rest during the glissando. The glissando eventually sounded to the first rest in the next bar, which is not correct.

And in this case, there should be a notation for glissando with note-values designations above the staff.

Such note-values should be set automatically, and the glissando should sound not with the duration that indicates the note from which it comes, but with the duration that the glissando line is drawn.

Prior art

As far as I remember, there is 100% such a notation method in Finale.

Additional context

No response

Start by reviewing the existing harp glissando notation and playback behavior in MuseScore. Determine how selectable notation styles, automatically displayed note values, and glissando duration across rests should work; done means the requested notation options render correctly and playback follows the drawn glissando duration.
