How to use 1 button to turn on or off 2 devices at same time.

I have a Sofabaton U-1 remote. I would like to be able to use 1 button to turn on or off 2 devices at the same time (which my old Harmony did). As examples; A) In TV device model use 1 button to turn on or off the TV and the audio processor. B) In streaming device mode use 1 button to to turn on or off the streaming device and audio processor. In this case, the audio processor is older and does not support ARC. I like the U - 1 but without this ability it does not work for me and I ned to return it to Amazon.
