"Drill Across" in PowerPivot - Live Demo

The retailer overlap application is one that I've covered before, in my post announcing our live PowerPivot demo site, but I've recently spent some time improving it based on customer feedback and requests.

Specifically, our retail customers have asked the following: "It's great that I can see that Retailer X competes with me for our senior citizen customers much more aggressively than we thought, but can I get a list of the actual stores that overlap, with addresses?"
