Topic: UCX II Main vol knob control Line OUT 1-4, 1-5 and 1-6, not only pairs

Hi all,

I'd like to control surround monitor setup volume with main volume knob on the UCX II or ARC in CC-mode (cuz Linux), but it seems to be hard-wired to either Line OUT 1/2 or 3/4 or 5/6 only - configurable in SETUP/REV -> Control Room -> Main Out. I guess this post https://forum.rme-audio.de/viewtopic.php?id=35711 kind of confirms it.
It would be a nice feature in the CC FW to be able to configure which OUT (pairs) the main volume knob does control - although just one more option "Analog 1-to-6" combined for Main Out in Control Room would save the day... as 1/2 or 3/4 or 5/6 are there, for the sake of completeness I miss options 1-3, 1-4, 1-5, 1-6 (and eventually similarly ADAT 1-to-8, could be selectable too, as AES and SPDIF are already there).
Having volume control per channel in CHAN/MIX and Room EQ already there, it would be a killer feature and could save all the Linux people a need for dedicated surround monitor controller.

Best wishes to all.
