Let's say you added the animated Captions first, then added a lot of scenes. Then there is no way to update all the Captions across scenes any more. Although I am able to select the captions and it shows it for the full composition, as soon I make a change, it just applies to the caption in the current scene. This means, I need to go through each scene separately to copy past the attributes to the caption manually.
