Travel Authorization attached to an Expense report is not visible to the approvers or auditors

Summary:

Our client has a requirement that the Travel Authorization that is attached to the Expense Report should be available for the Approvers and Auditors to view it. But currently the Travel Authorization number is visible to the approvers..

Isn't it a very common requirement for the approvers to atleast view the Travel authorization amounts and other details?

Is there any way to achieve this? Please suggest.
