It would be cool to be able to assign an item type to storage so that it only holds that type of item.
Ex: If you could assign a different resource type to each column of a medium silo (or the silo as a whole) so that when you output materials to it, they would appear in the column that has been assigned to that material type or if the storage does not accept that material it would not be stored there.
Simpler example: Assign a medium storage to only hold resin. Any other materials would not be able to be placed on that storage.
