The reimbursement policy includes a toggle named 'Batch Travel Expenses'.

• When the toggle is OFF, trip-related expenses are submitted one at a time for approval and set to status ‘In Review’.
• When the toggle is switched ON, any expense submitted to a trip budget are marked as 'Pending'.  Once a traveler submits their trip expenses (i.e., ‘closes a trip’), all the expenses in status 'Pending' are set to status 'In Review' and trigger the Expense approval workflow. 

In the following example, Reimbursement_1, Reimbursement_2, and Reimbursement_3 were submitted when the toggle was ON while Reimbursement_4 was submitted when it was OFF. Reimbursement_1, Reimbursement_2, and Reimbursement_3 will change status when the traveler ‘closes the trip’.
