Have the ability to make a "void" subroom. In the void you could build props that could then be used in other subrooms without taking ink until spawned in. There could be a get object from void that would have a vector, a string, and an execution. It would output a success and failure execution and an object port. When the chip receives the execution it would spawn the object with the tag that was written in the string. It would spawn the object at the position the vector lists. There would also be a send to void chip that would take an execution to send an object to the void. A use for this would be RPGs because right now it is almost impossible to have multiple weapons and weapon types due to ink. If I wanted a weapon in an rpg I would have to have that weapon in every subroom.
