Unless it uses the Spriter framework it would be limited, as Ashley had to modify a few things in C2 to allow importing multiple files at a time.
Otherwise you would have to import all the image files manually, and give each one a behavior.
Likewise you would have to create events to associate those objects to act as one, or create a family for each multipart object.
All the behavior would be good for is telling all the parts what to do.
Coincidentally you would probably have to import that data at runtime.
