Add two or more accidental on a note
In microtonal music, it need this indication. Especially in 『Helmholtz-Ellis JI Pitch Notation』, this notation is absolutely necessary. It would also be useful to create microtonal plugins if this feature existed.
Of course this can also be drawn with Symbols, but this will have to set the spacing manually.
The picture on the left is a five quater tone sharp of 24-Edo. On the right is the Harmonic seventh chord (C:E:G:B♭ = 4:5:6:7, Helmholtz-Ellis JI Pitch Notation).
Comments
The usual reply to requests like this seems to be:
"Until the symbols are available in SMuFL (Standard Music Font Layout), they won't be supported in MuseScore"
But you state: "Of course this can be drawn with Symbols, but this will have to set the spacing manually."
In MuseScore, both Extended Helmholtz-Ellis Accidentals and Wyschnegradsky Accidentals already have their own block in the Symbols section of the Master Palette (shortcut Z).
So what are you asking for?
Option 1 combined pairs of microtonal accidentals to be added to the SMuFL standard
Option 2 microtonal key signatures to be added to MuseScore's Accidentals Palette, along with defined spacing and positioning rules for microtonal accidentals
For the first option, ask the folks at SMuFL: https://www.smufl.org/discuss/
For the second option, I'll leave it to MuseScore developers to comment - it sounds like a major undertaking.

My thought is this. This is closer to option 2.

Adding another accidental to accidental.
For the option 1, there are too many kinds of accidental. Therefore, I propose the option 2.
in the case of parentheses, it would be better to wrap all accidental on the left of the dragged place by the user, and then to drag another accidental to the left of the parenthesis so that another accidental is attached to the left side.
If this is difficult or impossible, it would be nice to be able to attach 'symbols' to accidental as well.
For reference, the overtone written in 'Helmholtz-Ellis JI Pitch Notation' is as follows.
