Ability to select model on mobile app

I love that there is now a mobile app, but the limitations make it nearly impossible to use. I’ve tried using the guided writing and rewrite features but the quality and consistency of prose that it produces is not comparable at all to the web app. It doesn’t follow direction as well and gives mediocre results. I’m not entirely sure if this is that case because of whatever model is used on the mobile app, but it would great if we could select the AI model we wanted to use.
