@inject with default value (optional service)

In nette 2.0 i used to write optional services as:

<?php

function injectService(Service $service = null) {
	$this->service = $service;
}

?>

That make Service optional (If service was not defined in config, it has default null value).

Is any way to do that with @inject annotation?

This doesn't work:

<?php

   /** @var Service @inject */
   public $service = null;

?>

And I know that I can use old style, but I would like use this with simple @inject annotation.

(Sorry for my bad english:))
