calling all satellite radio experts

I could  use a little help with a question that I have about Sirius radio.  My girlfriend just bought a new Jeep with the MyGIG system in it and it has some great functionality on her Sirius radio.  When a song or artist comes on that she likes she can add it to her favorites and whenever that artist or song comes on again it will prompt her.  When the prompt comes up she can either tune to it or just ignore it. 

The question that I have is there any aftermarket (Pioneer, Kenwood, Alpine etc) headunits and SIR tuners that will allow for this functionaity?  I cant really demo this functionaity at my local store becasue no one has them hooked up to satalite.  I know some tuners have the game prompts for when your favorite team is on.   Is that the same thing? 

I know for a  fact that the Pioneer z-120 (Last years navigation model) does this with the GEX??920 XM tuner.  I do not know if the Sirius unit does this.
