Groups can be used to identify buildings with different addresses that belong together, such as building in a business park, or industrial park. The label that is used to group the buildings together does not appear on the leasing pages, but is a searchable term. 
To add a building to a Group, click on the three dots on the right-hand side on the Portfolio page. The dropdown menu includes the option to add a building to an existing group, or create a new group. Groups can also be created under the Information tab in the address section for a building as well as removed from Groups.
