You can already do this.  You filter the collection by console and you will see the total value for that portion of your collection.  Here is an example for my admin account:

What are these boxes called in Pokemon world?  Blaster box, wax pack, etc???  I'll look into adding these if you can give me a bit more info about them.

You can use the 'contact us' page to send us an email about any missing items.

We have some automated methods to grab these sales and admin can add them.  Can you please give me a link to a sale that we are missing and I'll look into why and see about adding the functionality for users to add these listings too.

Good feedback.  I'll look into separating those two for reviewing sales. 

Closing in favor of the original request.
