Are we any closer to straight mutes for trumpet?

Nearly a year ago, someone who works on MuseScore told me that straight mutes for trumpets was very close, but I still don't see it. Wondering when this feature is actually planned?

For those who wonder what I'm talking about, when you mute a trumpet in MS, it is a Harmon mute, not a straight mute. Mutes are not at all about volume, but about tone color, and the tone color difference between these two is profound.

For me, this continues to be the biggest hole in the otherwise excellent playback features of Musesounds.
