Manual Selection of Payment Approver During Payment Batch Submission

We have a business requirement to allow users to manually select the payment approver while submitting a Payment Process Request (payment batch). The expectation is that, during payment batch submission, the user should be presented with a List of Values (LOV) containing eligible approvers and be able to select the required approver. We are considering whether this could be achieved through a Descriptive Flexfield (DFF) or any other standard Oracle Fusion functionality. Could you please advise whether Oracle Fusion provides a standard solution to support this requirement? If not, are there any recommended alternatives or extensibility options that
