Add a "damaged" sold tab

Add a "damaged" tab to the section where you can view Ungraded, PSA 7, PSA 8, PSA 9, PSA10.  I assume there is some algorithm which searches sold listings on eBay for keywords (PSA10, Damaged, etc).  I feel like there needs to be a damaged tab so the prices for damaged sales stop wildly affecting the section reserved for (what i feel) should be LP/NM/M cards (currently the "ungraded" tab).  My example is my Venusaur EX from Pokemon Fire Red Leaf Green.  NM sales are upwards of $200, however many of the cards sold are HP/damaged which has brought the ungraded "value" of this card to an average of around $60, which is not indicative of the actual value for a LP/NM/M card.  Ungraded card tab should be divided into damaged/HP and LP/NM/M.  It seems like this sort of change could apply to all categories of collectibles on the site, not just trading cards, and would not take an extreme amount of programming to accomplish.  Thanks for reading.
