Can you add a field to input the package name for the iOS app and a separate field to input the package name for the Android app? That way I can just put both package names in SAB at the same time and SAB grabs the package name for Android when I tell SAB to create an Android app and SAB grabs the package name for iOS when I tell SAB to create an iOS app.
Because some of my apps are legacy apps for one app I have a different package name for iOS and a different package name for Android.
