Options for converting processed requisition to purchase order

Hi All,

Business Requirement: We need to find all the approved requisitions or req's in process requisitions screen which are entered in fusion UI and generate orders in bulk. Users will only enter requisitions through self-service procurement.
Three options we are considering:

1. Touchless buying - working as expected
2. FBDI - We can see only two FBDI templates, one for creating requisitions and other for purchase orders. When tried to use requisition import, it does not let me load the approved requisition because it already exists in the system (which makes sense, as it shouldn't let me). The purchase order template does not have requisition# column to enter it. We are required to show req# on the order created, when we import the order with req#, the requisition status should show ordered or processing order.
