Please let me use my decks for Sortie runs

Can we please get a special Sortie or similar Chaos where I get to use my decks? We spend so much time building decks and it would be nice to use them more, especially in Chaos. Make the Chaos crazy hard. Just let me use my decks!! Instead of giving us cards / equipments, maybe just let us modify the deck a little after a boss fight? I know this is similar to Tower but Tower gets boring after beating it once.
