Having camera or lights look at points relative to models or sub-scenes painted into current Scene

[JulieWinchester]

The camera/light property lookAt can have as a value as Specific Resource object. The current Prezi 4 draft text says regarding this Specific Resource:

If the value is a Specific Resource, the source container for the Specific Resource must be painted into the current Scene, and the Specific Resource selector should identify a point or region in the source container. In this case, the light or camera resource should be rotated to face the point or region in the source container where the point or region is located within the current Scene’s coordinate space.

I think it would be useful to allow the Specific Resource to select a point in a painted model annotation's coordinate space, or to select a point in a Scene that is being painted into the current Scene via nesting (a "sub-scene"), etc. This would allow for orienting a camera toward a point that will later be transformed or placed elsewhere. The text could be changed like this:

If the value is a Specific Resource, the source for the Specific Resource must be the current Scene or a container or resource painted into the current Scene, and the Specific Resource selector should identify a point or region in the source container or resource. In this case, the light or camera resource should be rotated to face the point or region in the source container or resource where the point or region is located within the coordinate space of the source container or resource.
