Zend Expressive: how to change layout using Zend View

Zend Expressive defaults to layout template when using Zend View. I note the addTemplate($template) function in PhpRenderer class but where and how to add an alternative template to layout?

In a middleware factory of an action, in the action itself, or somewhere else?

Passing layout key to render() method of the renderer in data array seems like enough to switch layout just before returning the response.

For example:

class HomeAction
{
   public function __invoke($request, $response, $next)
   {
     $data = [
        'layout' => 'layout::default',
        // or 'layout::admin',
        // or 'layout::alternative',
     ];

     $body = $this->template->render('app::home', $data);

     return new HtmlResponse($body);
   }
}

I strongly recommend watching of repository and it's issue updates on github.

See #314 and #317.
