How to find/filter *.wma songs with missing album art?

Is this possible with MP3Tag?

If I drag and drop in a bunch of folders worth of *.wma files, how can I use the filter option [regular expression?] at the bottom to determin which individual files are lacking embedded album art?

If not possible w/ MP3Tag any other suggestions? I have some albums whos songs didn't get the art embedded properly through WMP11. Thanks -
