In ESS can Travel Request/Expense created on behalf of another employee

Hi Experts,

We have one scenario in ESS Travel

Secrectary creates travel Order/Expense on behalf of Manager ( CEO, MD etc)

Is this scenario possible in ESS Travel Expense.

Generally in today's busy life CEO & MD's give all the travel related work to their assistants. Is there any option available for secretary to open a travel order/Expense in ESS with out taking the credentials of his manager. I mean any admin authorization where he can create travel for his boss in ESS.

Thanks in advance
