App expose - only show windows in one desktop?

Just curious if anyone has found a way to get app expose to only show windows in the current desktop in Lion.

In SL if you input the following terminal command then when you activated app expose it would only show you windows for that app in the current space instead of all open windows in all spaces.

defaults write com.apple.dock wvous-show-windows-in-other-spaces -bool FALSE

Mission Control has replaced all window expose and is currently the only way to see everything that is going on within a single desktop (with the exception of minimized windows). But unlike All window expose, with mission control you can't easily see individual windows of a single app. Only App expose now provides this function. If I have 6 pdfs open on one desktop and another 6 pdfs open in another desktop (and presumably since I'm using 2 desktops I'm using these pdfs for different purposes) if I want to quickly switch to one of them using some form of expose it is really easy to accidentally switch to the other desktop (which I find very jarring and disruptive to my workflow).

Please note I am not trying to bash Mission Control. I actually don't mind it. I was just curious if anyone had found a similar terminal command or hack that restored the functionality of restricting app expose to a single space in Lion.

Thanks in advance!
