Include prices for steelbook cases as a check box, or adding a separate section for them.

Many collector's editions of games include a steelbook case as a limited or exclusive item that is heavily traded and sold in the aftermarket on eBay and personal ads. I believe many of them have a significant value that can add another layer to the item checkboxes for included items (such as box only, manual only, loose items, etc). It could also be included in a separate section like the Figures tab as well. I have many of these cases myself and would love to be able to have prices tracked for them and have a way to keep an updated list of the ones in my collection. Thanks for your consideration! :)
