Counting signed cards per deck

Is there a quick way for me to get the count of signed cards in each of my decks?  As best I can tell I have to either count them all by hand, or export decks to Excel and use some filtering and formulas.  This works, but I have ~3 dozen EDH decks and when I get new signed cards I'm often trying to put them in the decks that contain the most signed cards as I work towards getting fully signed decks.  Having to jump through hoops for so many decks is very tedious.
