You can already do this. You filter by sport first. Then you filter by 'Set'. Here is an example collection with that filtering.
This is only 1991 Score cards in the admin test collection.
Hi. Love your site and all the new tools you have added. I was hoping you could add an additional way to sort within a specific set (of my collection). It would be great if you added "sort by card number". I am more of a number order guy rather than an 'abc order' when cross checking the cards I have entered into my collection on your site. Thanks and Happy 4th of July weekend!
