End of Matinee camera matching?

I have a level that loads and launches an intro Matinee, when the Matinee finishes and, the viewport ‘jumps’ from not knowing to stick with a camera (2 cam setup).

How can I tell my Matinee/Blueprint which camera to hand the viewport off to?

I would like to keep my ‘camera_2’ viewport the Matinee finishes with since the Matinee is the intro to a menu screen.
(Im pretty sure this is a Blueprint function but not getting anywhere.)

Thanks for any advice/pointers in advance!
