The current Equip web app does not have a Designations settings page or an Add Designation action. Older instructions and screenshots for those controls do not apply to the current interface.
Organize participants in the current app
Use Groups to organize participants into cohorts, activity groups or other collections. With permission to create groups, open Groups, select Create Group, name the group and add its members. Turn on Enable Chat only if the group should have a conversation, then save with Create Group.
See Creating Groups for the full workflow. This creates a group; it does not migrate any historical designation data. Ask the Equip team if you need help interpreting an older designation.
