You mean without the regular track fader in between? Not sure in that case. You could have one in the inspector, undock the console and slide it right up next to it I guess?
Hang on, sorry I just reread your title. I thought you just wanted two PCs visible next to each other, do you mean you want the QC flyout on two channels? If so, yeah I think the only workaround is one in console, one in inspector.
That or use something like ProQ2 or Equality ;)
I like them top to bottom, actually.
