Auto battle could be better

One thing in pq3 that would be good is when you have run out of keys and all of your chest slots are full is you just go for xp to lvl up your citadel.
I would like to salvage every chest in an archive chapter and leave my character on auto battle for the whole chapter instead of having to salvage every chest after every battle it is a grind.eslecially as I need around 15000 to 16000 xp now for one citadel level it would just be nice to leave it on autoplay
