How to import third party assigned check numbers into Oracle Fusion to generate positive pay file

Content (please ensure you mask any confidential information):

We have an external service provider printing checks for us and assigning the check numbers. We are required to import these payments into Oracle Fusion and generate a positive pay file so we can complete our bank/cash reconciliation. We understand that for standard PPR payments in Oracle Fusion, check numbers are system controlled and auto-assigned. Given the volume of checks, manually overriding each check number before payment confirmation is not feasible. Is there any other way to bulk import third party assigned check numbers into Oracle Fusion so we can generate a positive pay file?
