To schedule a future job, put in the Appointment Time at dispatch as shown below.
The appointment will appear in the Appointments list and will be colored green. These jobs will always be organized in the order it was created and not by the appointment time.
The color of the job will change to yellow and be filtered into the Unassigned list 1 hour before the appointment time. The job will appear in the order it was created. So if it was created a few days ago it will probably be at the bottom of that list.
To dispatch the tow to a driver you can drag and drop the call on the name of the driver in the second column you want to assign the job to.
When the appointment time has past the job will change to red. The job can still be dispatched even after the appointment time has past.
