It's not an "auto choice" if there is a simple ui element that says "send all supplies to camp". A simple right click multiplied by hundreds of pieces of food becomes an annoyance. This isn't a survival game, the point of making food a resource for resting isn't to add micromanagement into the game. It's to curb the unlimited resting to more closely adhere to 5e.
You can literally right click on the items and send them to camp. Its just not that hard.
I do second your idea of selecting multiple items though.
