Set Link in Statistics Table (for example) for Unknown Property

I've noticed that if you have a Statistics Table portlet (2 dimensional) created, and if it can't figure out the the required values, it creates a "None" column that contains the number of unknown issues affected. That's great, but why don't we give that number a link so when it's clicked it shows the offending issues? Right now I pick the entire list and then have to sort through it and edit the issues to have the right values set.
