How to adding in existing Standard Purchase Order from NEW AWARD LINES after completed NEW SOURCING RFQ?

In user guide I find only add to BPA "If the outcome you specified on your negotiation is a Blanket Purchase Agreement (BPA), you can create a new BPA for each award, or add lines to an existing BPA by selecting an agreement number to which to add the lines. Proceed with caution at this stage, because you cannot undo your award decision after you click Submit."
