I'm not an expert in this, but I do run multiple monitors.  I don't
think you can do it with the standard software setup of gnome or KDE.
The monitors are always set up with a particular geometric
relationship that determines how you can drag stuff between monitors,
or even have a window span across monitors.  If you do a screen
capture, you get all screens as a single image.  This seems to imply
the monitors form a single workspace.

OTOH, xorg has the notion of multiple "screen" targets so I think it's
higher-level software, maybe the  workspace switcher or window manager
that determines this.  There could be software somewhere that does it
the way you describe.
