Ability to "Pin" a resource to a slot in a machine/container
Ability to "Pin" a resource to a slot in a machine, then Compulsive Sort will still work even if that slot is empty. Just use left click on the resource to toggle Pin status.
This would also be extremely useful if the container Sort function respected the Pin instructions. I often want to arrange a box in a specific order, but also want to be able to auto sort into MY specific arrangement.
