How do I change the signup field on my site's homepage in Edition?

Hey, y’all. Still working on our newsletter setup (the theme is Edition) and I’m wondering if there’s a way for the basic “subscribe” button on the site–the one which offers the potential for a paid membership–to be moved up from the bottom right in order to replace the open email field in the center. It seems like people don’t realize that they can get paid memberships, and we don’t want to drop a strict paywall just yet!

The website is if you want to see what I mean.

Is there any way to get rid of the open email field and replace it solely with the subscribe button?
