Quad Marching Cymbal Notation feature not there yet
I've since submitted the request to add the Quad Marching Cymbal Notation feature because in some song arrangements they notate them to have 4 pairs of marching cymbals (all different sizes) for a special sound:https://github.com/musescore/MuseScore/issues/22411 & since the release of MuseHub Drumline (Marching Percussion), it's still not added yet.
