Can there be a way to filter out runes that you already own (by own I mean have the max 9)?

It would make sifting through the runes for runes that you want much easier, if you didn't have to attempt to purchase them to find out you have the max already.

I think one thing that is always nice in life is to prove someone wrong so I would like to say I have 10 Greater Seal of Armor runes http://i49.tinypic.com/2rpz52e.jpg

I have 10 Tier 3 Magic Penetration Runes as well no picture because I'm lazy, but I have them!
