Smart playlist sort by Genius data status?

I have a very extensive library and would love to be able to create a Smart Playlist to monitor the availability of Genius matching data on all my songs. It doesn't show up on the list of query options currently - has anyone found a workaround to do this? If not, Apple folks - what can you do to make this happen?

Edit: I know "iTunes Store" isn't necessarily the best category for this question but it won't let me post it under the general iTunes heading. Mr/Ms Admin - if there is a better place for this, please feel free to relocate accordingly. 😉
