Can I add an Ad Hoc Approver or Reviewer to my PeopleSoft document in Workflow?

On Requisitions, the Creator can insert an Ad Hoc Approver or Reviewer at the Cost Center Level

On Vouchers, ONLY the Approver can add an Ad Hoc Approver or Reviewer.

On Travel and Expense, there will be NO adding Ad Hoc Approvers or Reviewers.

Note: Adding a Reviewer does not hold up the Workflow process, adding an Approver will hold up the process.
