Using Native Configs in Appflow to have different versions of app side by side

Have anyone used the Native Configs feature where you override the bundle id, and have it working on iOS? By working I do mean installed and running on a device; you end up with the 2 apps side by side on the device.

I have 2 different Native Configs and changed the bundle id for one; this works on Android but I can’t get it working on iOS.

NAME --> MyAppQA

NAME --> MyApp

I did have to create a new App Id with a wildcard e.g. no.myapp.* for the iOS package build to work… It now builds successfully.
I cannot add this file to HockeyApp (as a new app) and if I install this manually then it wont run and the icon is wrong etc.
That is as far as I get.
