Resetting mixer values

In my choir workflow I reset the track levels and track panning frequently to make different rehearsal versions.

It would be nice to have the ability to easily reset the levels to 100 and panning to 64 in the mixer.

In some other places in Musescore there are buttons to reset values to default. That's one solution. Double or right clicking to reset are other solutions common in software I use.

[Edit:
Double clicking the panning dial resets to 0. In my mind it should be 64 because that's the default value if you don't change it, it places the track sound in the centre and the little triangle points at that position on the dial.
Double clicking the level faders should reset to 100.

Oh, I'm using v. 3.3.2 and Ubuntu 18.04.3 if it matters.
