Yes - this is a new feature in Laravel 4.
Taylor has a good video on it here you can watch - which shows it in action and the code to use.
But in general you just add a filter to your constructor:
Class ExampleController extends BaseController
{
public function __construct()
{
$this->beforeFilter('myfilter');
$this->beforeFilter('anotherfilter')->only('getBoo');
}
}
