how to disable auto assigning PO number and manually enter them

Hi Gurus,

Need your expert advice..

 

We are implementing OCR for our AP invoicing and going through a testing phase.. we are loading AP invoices from last refreshed date in TEST and trying to recreate the POs wherever they are not available.. for the OCR testing to be successful, we need to use the same PO number that we have got on the Invoice.. But if we create a PO in TEST, it would assign a PO number that is different from the what we need.. Is there a way that we can disable auto numbering for PO and assign them manually to meet the testing
