Best Practice for Drop Shipment

Hello,

Currently we have drop ship items and internally fulfilled items defined in the same inventory organization. However lately we are facing negative onhand inventory in that organization which results in errors when receiving the ASN of drop ships. One of the solutions we are thinking is to create a new organization just for drop ships. Is that a good option? Do you know of cases where drop ships are catered from a specific organization (i mean not used for internal fulfillment).

Thanks
