How to retry rejected PO lines loaded via FBDI?

We have a legacy system that sends files of POs created. This data is loaded into FBDI and imported into SaaS using an integration to load the provided data into the required columns of the FBDI. Many of the PO lines fail due to discrepancies between the source system and the data on SaaS e.g source system says the item is on a specific BPA line, but on SaaS the item is sitting on a different BPA line.

The records are in PO_INTERFACE_ERRORS with Rejected status.

The Import Orders job produces the PDF output that details which records didnt load and why. However the volumes involved are significant and our customer has queried why there isnt a UI/ADFDI where the Rejected records can be modified and retried. Using the PDF to identify the failed lines and modifying the FBDI to try and reload the lines is very time consuming and requires alot of manual effort.
