Option to ignore octave transpositions when displaying in concert pitch

Your idea

A sub-toggle option beneath "Display in Concert Pitch" which allows octave transpositions (and octave components of compound interval transpositions) to remain when creating a Concert Score.

Problem to be solved

Concert scores ignore octave transposing instruments like Piccolo and Contrabass, and ignore the octave component of instruments that transpose at compound intervals, such as bass clarinet.
Currently, there is no way to do this. Octave clefs are not sufficient, as they are an outdated form of notation, and will export to parts, causing the parts to display at the incorrect octave. As it stands, it is impossible to create a proper concert score when instruments that transpose at or greater than an octave are present.
Creating this feature as a toggle would also allow users to turn these octave transpositions on and off, allowing users to view both at the sounding octave and the written octave.

Additional context

No response

Start by locating the existing “Display in Concert Pitch” option and the code that applies instrument transpositions when creating a Concert Score. Trace how octave and compound-interval transpositions are handled, then identify the relevant tests or add coverage for toggling octave components independently while preserving written-pitch parts.
