We recommend you update event profiles in your case rather than updating event boxes in Timeline. Changes are in almost all cases material to the case record and should be part of it so that case analysis and argument reflects that too. When you send any modified event(s) back from MasterFile, the existing event box in Timeline is updated automatically to reflect that.

Since the timeline event already exists, when you add the event to Timeline, it is updated as below.
