When creating a new dispatch, the Fetch button can be used to auto-populate mileage.
Once a start address and destination address are entered, click the Fetch button beside Enroute Mileage or Loaded Mileage to auto-populate those fields.
In the example below, the start address and destination address are 27.53 miles apart.

To view the route on a map, click view map (in blue). Clicking view map will open a new tab that shows the route in Google Maps.
Note: Auto-populated mileage can be overwritten. Simply type the desired mileage over the existing number.
