Possible addition

so, i play the Shamisen, a traditional Japanese instrument. the notation for the Shamisen is completely different from normal notation, and i was wondering if you could add a feature that switches to Shamisen notation, and some features. i made a group that was based on the Shamisen because i could not find a group based on that instrument, or that category at all. so i was wondering if you could also add a category for Shamisen with other instrument category's. it would be an AWESOME feature/addition/update for me, and other people on Musescore like me, or that general idea.
