Collection condensing quantity for identical scanned items

I am in the process of organizing my card collections while also continuing to add to it. This has created numerous instances of identical listings in my collection for the same card. Let’s say for instance I scan in 5 bulbasaur cards. I scan one of them, set the quantity to 5, and add it to the collection. Later after opening a pack, I get a new, identical bulbasaur. Once I scan it in and add it to the collection, I’ll have 2 listings for that bulbasaur. One listing would show a quantity of 5, and the 2nd listing would show a quantity of 1. Since i use the default setting for condition and i verify the set before adding the cards to my collection, they are identical listings that are separated due to the time they were added. 

I would like a feature that allows cards with the same values (i.e. condition, set, etc) in my collection to be automatically condensed. I would rather see a single listing for a card with the correct quantity rather than a bunch of individual listings from each time I’ve added that same card to my collection.
