Multiple inventory line items for the same card (I'd prefer they 'stack')

I scanned multiple copies of the same card but put them in different locations and assigned different tags. I think this resulted in not being able to stack them in my inventory, even after I subsequently changed the location and tags to be the same. I think the default behavior should be to 'combine' or 'stack' cards when they have the same productId (with the number owned reflected in totalQtyOwned).

I confirmed this behavior persists when exporting even without the differing columns, and I confirmed the cards have the same productId.
