After splitting your storyboard project, you may need to reintegrate the scenes from a separate project file. You can do this by using the Insert option.
- In your current project, in the Timeline view, move the red playhead to the point at which you want to insert the new scenes, or simply click a scene to select the insertion point.
- From the top menu, select File > Project Management > Insert.
The Open Storyboard Project window appears.
- Search for the *.sboard file you are looking for and click Open.
All scenes from the selected project file appear after the red playhead in the Timeline.
