I haven't tried it myself, but you could probably do it with a few sets of variables:
Variable Fam_Tivo set if Family_Room AND Family_Source = Tivo
Variable Kitchen_Tivo set if Kitchen and Kitchen_Source = Tivo
Variable MBed_Tivo set if MBed and MBed_Source = Tivo

Then in the feedback programming If Fam_Tivo OR Kitchen_Tivo OR MBed_Tivo set then show feedback state.
