To select all of the containers in a particular state or province in Territory Planning, there are two ways: adding the state field to the container-legend and using it to search and select from the legend, or using the selection tools and selecting them from the map. Adding the state field to the container-legend allows the user to filter containers by state and select all containers that match a certain state value1. Using the selection tools, such as rectangle or polygon, allows the user to draw a shape on the map and select all containers that fall within that shape1. Using the state/province selection mode is not a valid option, as this mode is only available for units(accounts), not containers1. Adding the state field to the unit-legend is also not a valid option, as this will only allow selecting units (accounts), not containers1.
