Ad Hoc Approvals in Expenses

Hello Oracle,

Is it possible to add an ad-hoc approver during the approval workflow process for Expense Reports, Travel Authorizations, and Cash Advances? We would like to know if this functionality is possible in the current Expenses implementation and whether it is available to both fluid approval (via the Approvals tile) and classic approval (via the Approve T&E Transactions or Worklist navigation). This functionality is currently available for voucher and requisition/purchase order approvals.

I saw a previous post from 2014 asking this same question and the reply from Oracle was that ad hoc approvals was not enabled in Expenses due to the extensive configuration required for Expense approval (e.g. approval privilege templates, etc).
