This would make it easy to sell certain systems, like vending machines or material refineries.
Could save also like storage drawers, lanterns, neon lights but require a two step filling process with the box from the store and the material you wanna fill it with.
The blueprint would show a schematic that looks just like the machine that was saved, but you would need to fill that schematic with a boxed machine. Like fill an industrial sander with industrial sander box.
