Expense Reimbursement Limit Per Employee

Summary:

My client wants to setup expense reimbursement for Business meetings or events per person 300USD . Reimbursement request will be raised by facilities management team and they will raise single request for 100's of employees.

We want to limit expense reimbursement per person 300 USD * number of employees

Currently in Manage Expense policies by expense categories setup I can setup limit per expense report/per year/Grade wise, but there is not option where I can setup is as "Per Person Limit(300 USD)"*"Number of Employees". Number of employees is variable and can change, but 300 USD per person will be fixed.
