We need to create the approval hierarchy for the responsible manager of the Cost Center in the approval flow of the Expense Report, the problem and I have not found how to make the approval flow for this process. The customer wants to add the cost center manager's hierarchy to the approval of the Expense Report.

So I would like to know if there is a possibility in the expense report to include approving levels of the Cost Center Manager in the approval flow of the Expense Report?
