I agree with the "compose them in post" idea, but there is an advantage to being able to send them all at once also.
Also, an advantage of doing it this way, is since it's in a different studio, you can switch the environment as well. If you're moving the camera from turntable, to macro, to ui, chances are, that same lighting isn't working well for all those shots. So doing it that way lets you light each shot with a new environment.
