Pro Q2 Request
That's exactly how it works now. Once in mid/side mode, you have the option to affect the mid, the side, or both. So, you already have the option to set only select bands to any operation that you choose. I suggest using the help file and really digging in. This plugin goes deep.

One thing that you can't do, is having one band affect only the L or R channel, and another working on M or S. If you really need that, you need to put two Pro-Q 2's on the same track.

Hi Fab
I relay like the ProQ2 and use it a lot. Sometimes I wish that it was possible to make a single band (not the whole plugin as possible now) working mid/side instead of left/right.
And idea for som further development - perhaps.
All the best
