Control where the customer's rotating subscription is on the rotation cycle
Authentication
The rotation product is required. This is because we support sku swapping from one rotation product to another in the subscription. When swapping to another rotation product that has no past orders, the ordinal is kept on the old rotation product. The new rotation product will start at the initial delivery product from that rotation (ordinal=0)
