Can we prevent Auto PO creation for only B2B Purchase Orders when we implemented Touchless Buying

Summary:

We implemented Touchless Buying as we have BPA'S in place. So when ever Sales orders (Dropship/B2B) created automatically it creates PR and PO'S and send to Vendor.

But in B2B Order flow Supplier/Site derived from Sourcing Rule and we can't update vendor details at PO level.

We have a business requirement to change the Vendor at PO level when Required (Only for Back-to-back Orders).

In dropship we don't have any such Problem as we are providing the latest Supplier/site while creating the sales order and here we need Touchless buying.
