merging objects or worlds

I have a group of Girl Scouts that are just starting to work with ALICE,
after they start creating their objects in their worlds, is there a way for me to merge what they have created? Take an object and its events in one world created by one user, and merge it into another world, with its own objects and events? What Im after is to create a group collaborative final "movie" of the events/objects the girls create individually, so that they can see it all together.

Is this possible, maybe under an import world, or import object type of feature?
