Filter/Sort for Game Ratings?

Is there a quick way (or a way to filter) to view games I have played that I have not given a rating to yet?

I can view a list of all my games, I can view a list of my games I have rated....it would be nice to a have a filter that would allow me to see those I have played but not rated yet. Perhaps it exists and I'm just not seeing it, but if it doesn't exist, it would be a nice addition to have.

Just a thought...
