It's more then a workaround, actually, as it may allow you, in a single event sheet, to decide what to include.
This is what I did in my current project, allowing to switch from a mechanic to another in a single layout.
(one side is a track editor, the other side is driving the car in the track we just made).
The user can switch back and forth, staying in a single layout, and accessing different HUD and actions according to the included event sheet.
