Multi Output Selection (1+3, 2+4 etc)

It would be great if we had the option to multi select the Outputs in a row.
Like if we want the guitar to be on 1 and 3 and a vocal mic on 2 and 4 that would be great, instead of having only stereo pairs or mono options.
One workaround I see is to create two rows for the same instrument, which is not ideal if you have more then 8 blocks and 2 different instruments setup.
Another option I guess is to use TRS to XLR outputs for 3 and 4 and use that for a mic output, but still it would be so easier if we had the multi select option.
