U-verse remote & Sony receiver question

Hi, recently got AT&T U-verse & have successfully programmed it to control all my devices (Sony HTSS360 5.1 channel Home Theater System, Sony BDP-S360 1080p Blu-ray Disc Player). So, right now the U-verse remote successfully turns on each component, controls the volume through the receiver, & controls the BD player. One thing remains: Can the U-verse remote switch the modes on the Sony receiver (satellite, BD, etc)? I'm still having to use the Sony remote to do this function (to toggle between modes). I'm just happy to have gotten THIS far. If this is the worst I have to deal with then - I'll take it. Any comments/advice is welcome!
