Create 1 Inbound Delivery for multiple POs using API

[Expert]

Hello, we are using API Inbound Delivery (A2X)(https://api.sap.com/api/API_INBOUND_DELIVERY_SRV_0002/overview) to create inbound deliveries in the system.We tried using the same payload to create 1 ASN for 2 different purchase orders with the same suppliers and the system gives error "Specify the same purchase order number for each item". When we try to create the inbound delivery in SAP, it works fine. Also when use the API to create 1 inbound delivery for 1 PO, it works fine.  Any way to use this API to create 1 IBD for multiple POs? Thanks!
