I would like the ability to convert all Live Captions to Static Captions. Currently, you can only do one at a time by selecting the caption, and selecting the menu item to convert (or create a hotkey).

When working with a long document with a lot of images, you can't use character styles with Live Captions. But once you convert to static captions, paragraph styles can then call character styles (nested, GREP). If you have a long book or catalog with a lot of images that rely on up-to-date captions, but then require character styles (for example, an image from a movie, where the movie needs to be italicized), you keep the caption live until the end, then you have to convert to static captions.
