You can view spreads in the built-in PDF Viewer, but you can't yet choose "spread" as a "finishing" option (instead of 2-up). It would be relatively easy to add that as another option, BUT it will certainly confuse some simpler users, so I am trying to understand why you wouldn't just print it as a booklet (2-up) and review it.
Another option would be to tell the printer to place 2 pages side-by-side and get the 'spreads' that way - but again, I'm struggling to understand how this is helpful (or better than a booklet).
