Something about Player Interfaces. I read people mentioning them, but I never tried myself.
Apparently, they're a block tied to your inventory, so just plug it into your storage system, then go nuts with opening bags.
Or an Autonomous activator set to right-click, with a vacuum hopper feeding into your system.
Just tried the autonomous activator and it's using the bags and not spitting out the loots so warning to anybody else don't use that method
