Cords notation for Accordeon

Now using ctrl K for creating cord names. Problem is that all cords are converted to capital letters.
For the accordeon we use a kapitel letter for the base note and small letters for the cord name.
Like C c c c G g g g D dm dm dm or A a7 a7 a7
Is there a style avalebel for my problem
Currently usign crtl T and ad my cords as tekst.
This means I cant tronspose my partiture without having to cange all my cord mames

Thanks for any solution
