Is there a way to route an expense report for another approval after PrePay Audit and before releasi

We are currently using delivered ERApproval workflow and have 2 stages.  The first is the Expense Report HR Manager. All expense reports go to Stage 1.   The second stage is the PrePay Auditor and only expense reports exceeding a certain dollar amount go to PrePay Audit.  We will be hiring a new PrePay Auditor and would like for all expense reports to go to another level of review before being released for payment during the PrePay Auditor's training period.    Has anyone set up something similar using the delivered workflow and roles?
