Diorama tracking details?

I've been spending the last week or so tracking down achievements and working toward specific diorama objectives, but when looking at what I need to do for some of the diorama pieces, I'm kind of in the dark. Is there a way to find out what pieces you're missing from unlocking the diorama?

For example, I know that you need to win 10 matches in each mode of the original game in order to unlock one piece, but I honestly have no idea how many matches I've won in each of the various game modes.

Then for another piece (Fett?) you have to have a kill with every gun and star card, but I can't for the life of me figure out which one I've missed.

It would be great if there was a tracker similar to what they have for the Jabba contracts, but I haven't found any of that info anywhere. Does it exist?
