Creating Content Fragment variations automatically

Hi 

I have a requirement of creating Content Fragment variations automatically while creating content fragment based on Content Model

As of now authors need to create CF and then varations. But we want some variations to be present when they open the CF after creating.

It was achievable with Content Fragment templates, but it is deprecated and not suitable for out use case.

Another way is to achieve it with Java by Event Listener.

We are looking for better OOTB approach by avoiding Java.

If there any better OOTB approach, please let me know.
