I try to create registry key with the panel "Registry"

I select "Add key from registry" and select my registry key.

But, the path is not the same and add only the key

I need to write all key or import reg...
I would like to know if it's voluntary ? Because in my mind when i want to add key i want all path ...
Or it's possible to have an option "Save all path" or something like that ?
Best regards,
