Concertina (Chemnitzer and/or English versions) notations

I play a Chemnitzer concertina that uses numbers and symbols to designate notes. I'm also interested in the English concertina that uses notes. For Chemnizter concertina players that do not read music, it would be nice to have a Chemnitzer concertina symbol placed with the notes as an option. I plan to read music myself, but learned concertina with these symbols.

Example: Note A=440. On Star brand Chemnitzer 104 button Key of C tuned concertina: Press "5" = A = 440 and Draw "2" = A = 440. Concertinas are tuned to different frequencies; I'm concentrating only on my Key of C box as the music itself can be transposed to other keys, etc. I may also be off an octave on the A = 440 tuning. It would great for MuseScore to automatically translate a score to the concertina symbols. The symbols include 1, 2, 3, etc., and +, 4/4, 1/1, 1/0, 2/0, 3/0, etc. for notes. ^ = press in. Symbols without the ^ mean draw out. I've been using the breath symbol for press in or draw out changes during measures.

It's not an accordian or bandoneon, but those are closely related instruments.

There are left hand, right hand press and draw different notes, and various button configurations for different types of concertinas.

Would any MuseScore software developers be familiar with this and be able to help me develop a concertina-based support system in MuseScore? Presently, I use the "accordian" staff and change it to "concertina."

There's a lot more involved with this because the 19th century Wheatstone English concertina (for which classical music was composed and Guilio Regondi was famous) uses a different keyboard and is unisonoric (same note press or draw), but the German Chemnitzer types of concertinas (used in mostly in polka or folk music bands in the U.S.) has different numbers and configurations of buttons and is bisonoric (different note press or draw).

I play a 104 button Star brand streamline style concertina, but there is overlap so it doesn't have that many notes. I plan to write music for my concertina with MuseScore and make it available for concertina players. The English style concertinas are different.

I'm also seeking to purchase a 130 button Star concertina that has a more full chromatic scale, and an English concertina to work on original classical music.

Anyway, I'm hoping there is someone that knows about the software development, and can help me to do this if it's feasible. I know concertinas are not as popular as other instruments, but it sure would help the future of concertina playing in the world if there was a way to easily covert and develop concertina scores.

I'd like to see more interest in concertina music and use of concertinas (of all styles and brands) for both serious musicians (such as renaissance of original classical concertina music) and the folk-based musicians. Reenactors of U.S. Civil War and other places in the world where the concertinas became popular could benefit from this feature.

I'm getting my squeezebox back from repairs this week and will work on my chromatic scale and keep using MuseScore to see what is needed. Presently, I'm using the note-text box and have to resize-redo these symbols whenever I change things as the text is not tied directly to the notes. I'm not adding any of my trials because I need to think this through more and develop a true chromatic scale for my individual concertina, which might be a bit different than others. That would mean any development of this feature might need to be changeable for individual concertinas, tuned differently, or that have different button configurations.
