iPod Auto Update Ratings

Hi guys, I have a pretty random question. I can't find any way to get this done; maybe you can help me out.

I have my iPod on manual update (too much music, too little space). What I'd like to do is rate my music using "My Ratings" in my iTunes Library and then have the iPod correct the ratings on those tracks in the iPod as well. Is this possible? (E.g. I rate "Chicken Dance" a 5 in my library, and also have that track manually added to my iPod. I'd like the iPod to show it as a 5 as well.)

I can't auto-update. I'd like to do something with smart playlists regarding the ratings.

My reply was deleted (?)

I am planning on doing smart playlists once I get the question above answered. I need to see if I can move ratings done in my library automatically to my iPod. I'm rating them after the songs are in the iPod.

I kind of think I just have to either 1) rate them twice or 2) delete the songs on the iPod and move rated songs back over.
