Sort *hot cards* in by set - Feature: sort cards in a set by number of recent sales

Feature request: I'd like to have a feature that allows me to view a year and set, then sort by recent sales. Ideally it would have the option of 30/60/90/180/365 days, but 90 or 180 days if I had to choose only one.  The feature is currently in the "Hot Cards" list, but is only available for single cards. I'd like to have this same view, except for within a single set. 

Value Prop: Collector has significant cards from a single set. We'll use 1991 Upper Deck baseball for this case. User would like to be able to see which cards out of the 800 card set actually have active sales.  If a card has zero sales in the past 6 months, I don't want to waste time posting it for sale or the money it costs to post on ebay. My example of 1991 Upper Deck cards comes from my own collection of 3,000+ cards. I have several sets like this, and I'm sure many other do too, especially from the junk wax era. 1991 Fleer basketball, 1992 Upper Deck basketball, 1989 Topps football, 1991 Fleer football, etc. 

Site value: This is already possible with existing data, so the lift is lighter than a feature built from scratch. It could also enable revenue driving features such as a "sell yours now" with a one click to market. 

I'm happy to elaborate more if there are any questions.
