Different price tier for MacOS version of iOS app

Currently, we are selling iOS apps through the App Store, however we're looking to add a MacOS version of the app with additional features. We wan't to select a different price template for the MacOS version of the app, while keeping the iOS one as is, does anyone know if this is possible? I can't seem to find anything in the Apple Developer website that can do such a thing, so any help is greatly appreciated!
