For a game like Injustice 2... it's no secret on other consoles and even PC that there's a way to set up a macro and go into endless mode with an AI fighter, and have the macro hit the action button after every match to keep it rolling to help with gear grinding and leveling up and whatever.

I'm wondering if anyone is aware of anything on deck that can do that for said game or similar titles?

I picked up Injustice 2 on the recent sale. Had it on PS4 for forever, put in a lot of time on that one and I'm just trying to find a way to speed up leveling and gear accumulation on the deck now. Would prefer to keep it on the deck and not my PC if possible.
