(Multiplayer) Test Join in Progress in editor?

Hi All, quick question, does anyone know any good tricks for testing player drop outs and late joins using the magic of Multiplayer in the editor? Its just nice to be able to quickly test such things without spooling up two VS standalone games.

Thanks!
