Provide a parameter for a custom template in SonataAdmin fields

[ma...@lamarciana.com]

I know how to set a custom template for a field in SonataAdminBundle, for example:

    ->add('parent', null, null, 'template' => 'NS:Admin/CRUD:show_entity.html.twig'))

But, how can I pass a parameter to use in that template?

Thank you
