Using Catalyst with an existing Mac App Store bundle id

I have an application that works on both iOS and OS X (as normal UIKit and AppKit applications). Now, I rewrote the app to accomodate a very significant backend change and now I'd like to avoid rewrite the UI on AppKit but just use the iPad app with Catalyst.

The problem is: the generated bundle-id for Catalyst app is on the form uikitformac.ios.bunde.id, can I change it to the existing Mac bundle ID so I can market it as an update to the previous app, that's what actually is?

Also, the iOS app uses CarPlay (audio) so I must use custom certificates (they cannot be managed by Xcode with CarPlay entitlements), can I manually generate the mac certificates for the catalyst app? I tried with Xcode beta 3 (or 4) and I didn't manage to do anything.

It's what I want to do even possible?

Thanks in advance for any information!

Did you find a way to achieve this?
