Request: Mute/Sourdine effect for brass

Recently I've been working on one of my many projects and I said to myself "Hey, there's some flavor missing here" and when I realized it I wanted to add the indication "muted" to the brass to give a bit of texture to my work. Mine was surprised when I reproduced the passage in question and it didn't sound as I thought. I checked that everything was fine, until I saw the features of the MuseSounds, and realized that it didn't include the "mute" effect.

So, my request for features in a future version of MuseScore, or, come to think of it, for an update to the MuseSounds, is to include the "Mute" effect for the Muse Brass.
