Extending the libraryAdd folders of your own .ffx animation presets, or use a project composition as the caption template. A project composition is placed once per caption, so it carries caption timing rather than the word-by-word timing the built-in presets useOne clip: the whole caption track on a single clip, split per caption when you want, and bakeable to a PNG sequence

The Styles, Effects, and Transitions libraries are smaller in Premiere, and a MoGRT exposes a fixed set of controls. If something looks different in Premiere, that is usually the platform, not a bug. The Styles Generator still grows the library with you: it produces new looks from any preset's settings, in both hosts.
