How can Expense auditor see which one is additional approver in the workflow

Summary:

We found that when approvers approved and route to expense auditor, expense auditor cannot see which one is additional approver(e.g. reassign/route by approver) in the workflow.

Content (please ensure you mask any confidential information):

Can we know which one is additional approver in "Auditing" page? Because our expense auditor may need to check the approval flow, and also when there is auditing on expense we also need to provide information for auditor. 

If user cannot see which one is additional approver in "Auditing" page, please advise any alternative way that we can check the additional approver in Oracle.
