With the convenience center and satellite prep options(satellite cable runs to every TV), a portable dish can be connected to one TV by removing the Trav'ler SWM cable in the convenience center and attaching the feed from the portable dish through to a receiver. If your Dish types are different between the roof and the portable unit, there will be some reconfiguration necessary within the receiver.

If it is the automation you are after, there is a portable unit out there now which will find the satellites automatically. I may never have gone to roof mount if that model had a DirecTV HD version.
