You will want to use this feature whenever you need to calculate travel time or travel distance between 2 different locations. The value returned can be populated to another Text field that you can optionally set to be disabled to not allow the user to edit the field.

This feature can be enabled for any Text field in your form.

Note: For Destination address or Starting address you can either enter a fixed address/zip code or enter the unique field name to retrieve dynamic location from user entered.
