Please track volunteer mileage

We need to track volunteer miles as well as hours for in-kind grant match for our projects. Currently there is no way to do that except for in the notes field - and it is messy and inconsistent. Having a dedicated field in the Volunteer Kiosk/Hours Worked for volunteers to report their mileage as well as their hours would be ideal. We value miles according to the federal mileage reimbursement rate, and this give us more match for more grant money, so it is very valuable data for us.
