anyone connect two rf remotes to one mini?

Does anyone know if two roamio rf remotes can sync simultaneously to the same ver 1 mini using the same rf dongle?



Or..



Has anyone got x2 BT ver 1 Slide remotes to work on the same mini? If so did it take both usb Bluetooth dongles or were both able ro connect via Bluetooth using the same dongle?



I've already tried pairing simultaneously one rf and one Bluetooth remote unsuccessfully.
