Create POs - if Entire Requisition Approved

We are currently experiencing a scenario with requisition lines sourced individually upon approval which is creating many PO’s for 1 order.

In our scenario, the Requisition is having multiple lines and each have their own workflow steps, so the PO Auto sourcing is creating a PO for each requisition line, as they are being approved(It is working as designed, I don't complain about).

This is creating quite a confusion when reporting, is there any setup/configuration that we have to avoid Requisition lines being sourced to PO until the entire Requisition being approved.

Any help is greatly appreciated!!

Thanks,
