Hey, Finnicum1! Chadt4141, and Jim5506 are correct. The favorites list can't be transferred from receiver to receiver. Each receiver has it's own Guide, and Guide Settings, so the Favorites list would have to be created at each receiver individually.
We are always working on ways to improve our systems, and provide a better viewing experience for our members. This is a great suggestion! I have forwarded this up as feedback for you, on features you would like to see available. Thanks for reaching out!
