Adding a Quadruple Marching Cymbal upgrade for the Marching Cymbal Instrument.

So I had this idea of upgrading the Marching Cymbals instrument in Musescore to feature 4 Different Sized Pairs of Cymbals (I refer to it as a Quadruple Marching Cymbal Notation) all w/ the same techniques but in various pitches because some of the Cymbal parts in Marching Band arrangements that are being published today (e.g. the Cymbal Part from Paul Lavender's arrangement of the Fanfare from E.T. by John Williams) call for 4 different sized pairs of Cymbals as they wanted a really special sound w/ more overtones & richness.
