Question about finished event of matinee

I want to check if my matinee is end, so I create a matinee controller of my matinee in level blueprint, then I add some action connect


d with Finished pin, But the Finished event seemed always doing, and i only need once.

the key is I play the matinee again trigger the finish. So how to change the matinee state? make it not in Finished state, I tested SetPosition not work.
