Q:

Extending package name android

I have a question about extending package name in android studio. I know how to refactor existing name to some other, but what i want to do is add one more extension. 
For example i want to change com.google.something.app to com.google.extension.something.app 
Is this possible to do and how to do it?
Thank you for your help
