Summed Mono?

I have read the manual a few times and I can’t seem to find the answer to my question. Is there a summer to mono output? Fractal has output options for L, L copy to R, Stereo and LR Summed. Kemper has some similar choices with something they call Master Mono which sums LR.

Does QC do summed mono? Like if I choose output 1 mono will it be summed? Or maybe if I have output 1/2 selected but only plug into the L? Or maybe there is another way to do it?

No one knows the answer or have similar question? Interesting
