The Quick Dispatch feature can be used in a few different ways. It is excellent in cases like snowplowing. Companies who need to instantly add a constantly changing group of customers to their schedule can get their crews dispatched quickly.
You can find this feature in the Team > Dispatch Board.
Use it as a "multi-add" where you can simultaneously add several visits to your schedule.
Create groups of customers that need the same services so you can quickly add them to your calendar on any given day.
Create a group of customers living in the same area that would be on the same route so you can quickly add the whole route of visits to any day.
