Is there a way for an approver to make adjustments to a Spend Authorization?

Summary:

Client would like the approver to have the ability to modify a spend authorization request. Currently, in order to adjust a request the approver must reject and the employee will have to make the adjustments and resubmit. We are hoping that the approver will be able to make these adjustments, even after approving the request.

Content (required):

Approver should be able to modify a spend authorization request at the point of approval (instead of rejecting and asking the submitter to make changes and resubmit). Approver should be able to modify a spend authorization request even after approval.
