What problem do you see this solving?
When I tether raw+jpg, Capture One shows the jpg "as last captured" (at least with my Sony A7R4 and A7R5). I would love however to be able to show the raw instead the jpg when I tether raw+jpg. Right now, as a workaroud, I have to set the cam, so that it sends only raw to the computer (like this, the cam even send jpg when I tether only jpg, send raw when I tether raw and send raw when I tether raw+jpg, but like this, the jpgs from raw+jpg are missing on the computer and I have to fall back and use the photos from the memory-card). I tried "global filters" but these are one format exclusive.
