The way I would do it is to copy 2nd L3rd group to the final scene. Then go back to 2nd scene right-click on the animation controller, select copy, then paste into the final scene's scene director; which triggers a pop-up menu where you can designate which object the pasted animation controller will be applied to.
Then I would go to the 2nd scene and I would open the visual logic window. Click on the Visual logic tab that applied to my lower third and under the visual logic menu (upper left) you can save that as a file (I save mine to the Misc folder). Then I would go to my final scene open the visual logic window, click on the visual logic menu (upper left) and select open.
As long as you're naming conventions are unique, this process should work. This is how I would do it anyway.
