As the title says. I'm playing a very quaint system that mainly uses decks of cards, but these decks have to be rearranged and some cards have to be stacked for certain decks. It's a very bothersome chore having to manually recreate every single duplicate card in a deck whenever I need to. Decks already have a (awesome) option for duplicating them, but I'd really really love if we could get a duplicate button for individual cards within a deck. REALLY appreciate it.
