With SmartMonkey Planner you can create zones for the same project and implement them in each of the schedules as needed.
In this way, you will be able to create as many zones as you need and use them or not in each of your plans.
How to create zones
Enter Project Settings
Create zone: with the pointer, create the zone on the map
Now you only have to assign a name and color and you will have the area ready.
Activate zones in a plan
For the zones to be visible within a plan, we must go to Plan Configuration and there enable or disable all those zones that we want to use.
Whenever a new plan is created, it will be created with the zones that are currently activated at the project level.
