So now there is some auto-replay to these battles. Each battle can individually record your clear and you can choose if you want to auto a battle or do it manually. Like in this image, the first 2 battles have a replay recorded for them and are set to auto but the third one doesn't so if I want to return to the 3rd battle after changing characters around, I can have the game replay the first 2 battles while I will regain control for the 3rd one. Still not optimal but it's at least something. Doesn't look like you can select how many rounds you want to auto-replay though. The game will only do 1 full run before stopping on the basic results screen. You'd have to keep pushing the button to do another round.
