You can merge (combine) two or more Events in the Event Library, which lets you keep your video organized in groupings that make sense to you.
To merge Events:
In the Event Library, do one of the following:
To merge one Event with another Event, drag one of the Events to the other one.
You can select more than one Event by holding down the Command key as you select Events. You can then drag all selected Events to another Event to merge them.
Select two or more Events by holding down the Command key as you select them, and then choose File > Merge Events.
The File menu appears in a light gray bar across the top of your computer screen.
Type a name for the merged Event in the dialog that appears, and then click OK.
If the Events you merged were recorded on different dates, the merged Event appears in the Event Library based on the date of the newest clip in the now-merged Event.
