Are Internal Requisitions possible in RSSP?

Can we perform internal requisitions ("purchasing" goods from one of our own facilities/storage warehouses and shipping them to another one of our facilities through a proper transaction) using RSSP? If so, how? We frequently do internal requisitions at our company using classic self-service procurement but can't seem to figure out how to use the new Responsive Self-Service Procurement to create an internal requisition. Is that feature available yet? If so, how do we do it? If not, when will it be? It is a dealbreaker feature for us.
