Smart Playlist -- Least Recently Played Albums?

Hi. While I like the "least recently played" function in smart playlists, I was wondering if there was a way to create such a playlist on the album level rather than the song level. Alternatively, does anyone have any ideas for creating a smart playlist that syncs up entire albums, either at random or according to some specific criteria? I wonder if there isn't some setting I'm missing... anyway, thanks in advance for your help.
