A GUI that allows to see extended desktops?

I have a machine with 12 video outputs, and I need to control what is on those outputs with out actually turning the monitors on. Is there a GUI that has that ability? Say thumbnails of the extended desktops which would allow a "drag& drop" on a single workstation to the extended desktop monitors.

Thanks,
