Repetition of the accidental when notating two or more performers on the same staff

Your idea

I suggest implementing a function in MuseScore Studio in which each note in the chord (as well as in each voice) has its own accidental and does not relate to subsequent notes belonging to other performers.
This applies only to those staffs on which 2 or more performers are notated. This does not apply to staffs for single instruments such as harp, piano, etc.
Thus, each note of a particular performer should have its own accidental, for example:

Problem to be solved

Choral music and orchestral parts often double up two (or more) parts on one staff in a score. Therefore, for clarity, it is necessary to confirm or cancel each accidental in every part. This guarantees that essential accidentals are not omitted when instrumental parts are extracted, or when different voices read from a single stave in a vocal score.

Prior art

As far as I know, both Sibelius, Finale and Dorico do this.

The issue names no source files, tests, or entry points. Start by locating the accidental-notation and multi-voice staff logic, then determine how performer-specific state is represented. Done means each performer’s notes receive independent accidental confirmation or cancellation on shared staves, while single-instrument staves retain current behavior.
