Create a Service Line from Order Import Process

Hello Experts,

I have to design an order interface to import two lines which are coming in a csv file.

Line 1 has ITEM 1 and LINE 2 has ITEM2 with relevant details in the CSV file.

Now line 2 is the service line for LINE 1 ITEM 1.

I understand the below columns help to create a service line

ITEM_TYPE_CODE='SERVICE' (Hardcoded)

SERVICE_REFERENCE_TYPE_CODE='ORDER'(Hardcoded)

SERVICE_REFERENCE_ORDER=Previous Order- Order Number

SERVICE_REFERENCE_LINE=Corresponding Previous Order - Line Number

However in my case i have to create a service line and the main line for the order at one go using the order import Program. Since the order will only be created after the Order Import process Is this possible to create a service line together in the first import ?
