How to get transit lead time on newly created address during order import

We are currently in the process of implementing Global Order Promising (GOP), with ASCP hosted on a VCP server and EBS operating separately. Accurate transit lead time is crucial for calculating the 'Scheduled Arrival Date.' Our system defines regions at the postal code level, and transit lead times are mapped to the lowest level (postal code) based on various shipping methods.

During order import from our e-commerce platform, B2C customer addresses are dynamically created. However, during the order booking and scheduling process, the system attempts to retrieve transit lead time based on the shipping method at the order line level. Since the customer address is newly created, ASCP is unaware of this location until the collection process is executed, resulting in inaccurate delivery lead time suggestions.
