Is there any way to determine current action (create or edit) in Sonata\AdminBundle\Admin\Admin::configureFormFields()?

I\'d like to create different fields configuration for create and edit actions in Sonata Admin Bundle.

Is there any way to determine it except checking $this->g

   // create
} else {
   // edit
}
