Item Watch List (Sales Speed)

Now I have noticed for stuff like Conquest items and Assault items etc., that you can not only see the price, but also the sales speed (Dead Slow, Very Fast, etc.) Now I like to create an item watch list of stuff I am selling whether it be crafted goods, old equipment or whatever, and I generally reference that list when deciding what to AH next. Going solely by price and quantity available is good, but I would love to see on that same page what sells faster to help me decide what to list next. I would assume it's not hard to do, as you'd just add one more field to display which is already available in the database, but regardless, it's a feature I would really welcome and get great use out of.
