In past events (on-demand videos) or recently completed/published events you can add highlights for those relevant actions that you might have missed to tag during the live streaming.
In either case, you can proceed as follows:
1. In the timeline you can scroll back until reaching the point of the video where you would like to add a new highlight.
2. Then, just add the highlight exactly as you would do it during the live event.
3. A new highlight will be added in the selected position of the video.
You can also edit highlights. For example, if you add a goal and select the wrong team or player, you can click on the edit button (1) and access the specific highlight manager as you can see in the screenshots below.
