One Application spanning multiple desktops?

[mikebridge]

When I run Visual Studio 2013 with Resharper's Test runner, on a single-monitor, it's really difficult to manage because it's always on top, it docks when I move it, and the shortcut keys to minimize it aren't all that useful.

Is there any way to set Dexpot up so that an application with multiple windows can span two (or more) desktops?
