SmartFill allows you to edit data that has already been put into the system. This is useful when you need to change a vehicle's registration or rename a SmartFill system to something more recognisable.

Just click on the field you would like to update, and a text box will allow you to edit the data. Type in your desired information, then press Enter or click away.

If you enter data that the website does not recognise or allow, an error will show explaining what went wrong.
