Again, this is Inventory Management issues, not Camping. The camping mechanics themselves are straightforward and simple. You collect food. You long rest. Click auto-select. Boom. Done. Simple and easy.
The issue is that Inventory is slow and clunky, so sorting food and sending it to camp and so forth is a huge pain because you have to right click on every item separately and Send to Camp or you get weighed down by food, of all things.
But again, this is the same issue we run into with ALL items.
