Simplify keys for transposed key signatures

When working on a piece in a 4+ sharps key, the Bb and Eb instruments end up with 6 and 7+ sharps key signatures. A setting that simplifies these is sorely needed (meaning - a C# minor Clarinet part should be in Eb minor, and not D# minor).

In the screen shots you can see how a D# minor part of a well known tune looks, and what happens when I locally change it to Eb minor and use the Respell Notes command - Dorico, for some reason, makes horrible respelling choices that would not be acceptible in any professional scenario (or even an amateur one, for that matter…)

Instead of changing the key signature, you could try to use Transposition Overrides for these layouts:

Alternatively: in your 2nd screenshot in Eb minor, select the notes, Shift+I, type spell ebmin, Enter.
