iOS Screenwriting Scaling on iPhone

While zooming in with screenwriting mode on my iPhone the formatting does not scale. For instance, in a .8 or .9 zoom the formatting looks proper with margins like in Final Draft, but not when zoomed in to 1.0 or more. Hopefully that makes sense. I’m just looking to increase the font size while keeping the proper margins, like keeping the character dialogues centered.

Is there a way to do this?
