Bring back "Mute", "Pizz." and other mixer tracks

Your idea

Please bring back the extra mixer tracks that brass (normal, muted) and string instruments (arco, pizz, not so sure about tremolo) used to have back in MU3.

Problem to be solved

Sometimes, you might want to balance out muted brass or pizz. strings because they're too loud/quiet compared to the rest of instruments (or their real counterparts).
Back in MU3 you could change those volumes independently of whatever the master volume of each instrument is, which was pretty handy.
Now, that feature has been removed from MU4, the only way I can achieve a better volume control is by adding some weird instrument changes to create those extra tracks. :(

Prior art

I've found the same issue on sibelius, they haven't really done anything about it from what I know, so I have to do the same instrument change workaround as MU4.

Not aware of how the situation is on the rest of programs.

Additional context

This also would solve the inability to select sounds from a VST/Soundfont and assign them to the Pizz., Tremolo, Mute and Arco playing techniques like in MU3.
