It’s just a case of editing the accidentals within the tonality system in order to use those specific glyphs.

Welcome to the forum diegtaph! As Leo says, you can edit the existing 24-EDO tonality system or create your own tonality system, either from scratch or starting from an existing one as a base. You can also export/import tonality systems from one project to another if you want to re-use a custom one.

Great to see that questions are ansered so fast and kindly.
Thanks again!
