MS Matrix for AXR4 - an option in "channel link"?

I really miss MS matrix option - it could be a simple “channel link” option - to link two channels and the first becomes MID and the second SIDE - it would be so much easier for monitoring than creating three channels in DAW for this and having latency… So, when I would right click on “channel link” - there would be an additional option that would turn those two channels into a MS matrix.

Or anyone can suggest an easy workaround for MS stereo recording?
