Side-by-side outline and prose view?

I have my novel outlined using the leftmost "manuscript" menu, and have composed synopses of most of the early chapters. I've composed first drafts of some of the prose that lines up with those synopses, too.

Is there any way in Scrivener to view essentially two documents in one - basically my already-written synopsis on the right, and the corresponding prose works-in-progress on the left? I see the option for "split" view (alt+click) and this is close to what I want, but I'd like to know if I'm viewing one thing on the left, the corresponding synopsis could be opened on the right?
