Create Drop Ship PO automatically from Drop Ship Requisition without Blanket Agreement

In a business scenario, we have some items that are considered pass through. So these are ordered by customer at $1 unit price and qty adjusted to reflect the amount.

The objective is to create a PO to a supplier with $1 unit price and qty from sales order line - which will reflect on PO Amount.

Planning to use Drop Ship process. The issue is that requisition will wait for PO creation:

1. Either it will be manual autocreate process to create a PO
2. Or establishing a Blanket Purchase Agreement as source - Auto source documnet profile = Yes

We want to avoid both and have the system create approved PO from the drop ship requistion.
