3819026 - How can I enable the "Send Back Expense" checkbox for Approvers and Processors?

I would like the ability to send individual line-item expenses back to the employee without having to return the entire expense report.  How can I enable the setting that allows my Expense Approvers and Expense Processors to selectively reject single expense entries and return them to the submitting employee?
