Is it possible to have a different background in each screen when using a 2- or 4-screen view?  Or when using a camera for that matter.  As an example, let's say I'm using the 2-view vertical layout, with the left view being anything, while the right view is through the camera (with integrated preview on, or using a preview window for PV360).  Is it possible to have the left view be "Studio room", while the right view (camera) is "black with fill lights"?

It's not really a big deal, just something that I noticed today that bugged me, because for some reason I can't stand changing anything in the model using a different environment other than the studio room one, but would like to see quickly how that change affects how the model looks in that environment.
