Shopify has limited space to what can be published on the app store, so just the most common features are listed.
Order Automator is a different type of app, in that it’s extendable and customizable, so stuff like this that’s 1-off requests you can contact https://orderautomator.com/contact with your store url and what you want to do exactly and support will take care of you.
Maybe we should add that extendable customization part as a key feature on the app page, good point
