Edit Single Event in Series
When making changes to repeat events, you will have the option to update all events in the series, or to detach and update this single event from the series and have the others remain unchanged.
When you click Save you will have the option to update all events in the series or to detach this event and only apply the edit to this single occurrence
If the event is detached from the series, you will see the chain icon with a slash through it
This is now a stand alone event and any further edits will not prompt you to choose to update the series
