Deck Builder to show # of cards in collection

Hi, me and my friends are trying to practice deckbuilding by using the pack simulator and the collection feature. Unfortunately, the deck builder doesn't show the amount of cards I actually have in my collection as I add them to my deck, so in order for me to keep track if if I'm adding more copies than I have in my collection, I need to have my collection open in another window. YGOPRODeck has a feature like this in their deck builder.
