A consulting firm is asked to add Events and Milestones to a Lightning record page...

Agentforce Financial Services supports this requirement through Unique event types. Events and Milestones provide advisors with an at-a-glance view of significant customer life events and business milestones so that they can understand changing client needs and identify timely engagement opportunities.

For an event that should logically occur only once for a customer, the administrator can mark its Event Type as Unique. Salesforce specifically states that this setting is intended to prevent users from accidentally creating more than one occurrence of the same unique event type.

The configuration is performed on the Person Life Event object ' s Event Type field. The administrator edits the relevant picklist value and selects Unique. Business milestones can be configured similarly by working with the appropriate milestone type. Salesforce also supports activating or deactivating event types, hiding sensitive events, defining contextual actions, changing icons, and controlling the details displayed when users interact with an event or milestone.

Once-in-a-Lifetime, Special, and Single are not the Salesforce configuration designation tested here. The supported mechanism is explicitly the Unique setting.
