Ability to Account for All Heritage Auctions sales

I'm not a fan of WATA or Heritage Auctions, but if PriceCharting is going to list Heritage Auctions sales, then all sales should be accounted for.  There are countless games that literally show 0 HA sales, but were sold at auction multiple times.  We need the ability to either automatically account for all of these sales and/or have the ability to manually add those sales.   With the huge uptrend followed by huge downtrend in prices for graded games, these complete trends MUST be available for PriceCharting users.
