question about eyefinity and 4 montiors and mounting 4th above

I currently run an eyefinity set-up and love it, but one thing I really miss from when I only had 2 monitors is having a spare non game window for movies/web browsing. I'd love to setup a 4th monitor above my center one for this purpose, how would this work?

Can't I set up eyefinity so that it will allow this (2 groups, one of a 3 monitor group and one single monitor group) so it will still launch games in eyefinity on my bottom 3. And if so, can I set the arrangment so I can just go up on my middle monitor and it will scroll up to the 4th, or will I have to scroll all the way right across my side montior just to get to the 4th?

yes, it does work, i currently have a setup exactly like that. mouse scrolling works like you think it would, up is up. Was a bit tricky to get the grouping to work right, at first it wouldn't detect the full resolution for my Eyefinity group when the top monitor group was setup, but i messed around with the settings for each group and got it to work, cant remember exactly how though (sry), think it was something to do with lower color depth on the top monitor then raising it again..
