Clubbing Auto generated purchase requisitions with & w/o Supplier details into one PO

Summary:

Question on Clubbing Auto generated purchase requisitions with & w/o Supplier details into one PO

Content (required):

We have purchase requisitions generated from Supply Planning module. We have the following scenario

1. Req 1 - Item X - With Supplier A and Site B

2. Req 2 - Item Y - with Supplier A and Site B 

3. Req 3 - Item Z - Without Supplier and Site (Not passed from Supply Planning)

All the three items X, Y and Z are sourced to the same BPA.

Since we have disabled auto-generation of POs from requisitions, Will a manual run of the Generate Orders program club the requisition 3 without supplier details with other requisitions into a single PO?
