Once you are on the Crew/Truck Dispatching Page you will see the option to leave a Day Note.
This is a note that would show only on the day that it was added, this note can also be branch specific so that you can have different notes shown depending on the branch you're looking at.
A day note would be, for example, if a specific customer needs to be scheduled early in the day or later in the day.
(EX: MOVE FOR "JOHN DOE" NEEDS TO BE SCHEDULED FOR A MORNING APPOINTMENT.)
