NO!! There is no fast and easy way to find out what you want. You can always ask for a new feature.
There is a report: Match items on your Wantlist with items on other members' For Sale / Trade lists. You pick the area (sport or non-sport) you want then you pick the set. It shows the players then several clicks later you can see the members with cards for you. (30 logged in or others)
Appears what you want is that you can pick the player instead of the set. Then it come up with the members listed with the most cards for you on top.
