More Jazz Brass Notation

Hello, I know Musescore has just updated however I would like to see more notation for bends, half-valves, and plunger/ "wa wa" mutes. I'm a trumpet player, so when I transcribe jazz brass players, they like to do alot of shakes and bends to really show their flexibility. I wish Musescore and Muse Sounds could include bends similar to the guitar palette, open/closed plunger notation, growls, shakes, etc. I understand there's some finagling I can do to get these things, however it'd be easier to have in a palette of some sorts. I hope to see this notation next update :)
