Can i use query in form builder to get filtered collection in symfony form

IN the AcmePizza BUndle this is working fine

->add('pizza', 'entity', array(
                'class'         => 'Acme\PizzaBundle\Entity\Pizza',
                'query_builder' => function ($repository) { return $repository->createQueryBuilder('p')->orderBy('p.name', 'ASC'); },
            ))

Can i do something like that in collection

->add('userTasks','collection',array('type' => new UserTaskType(),
                    'class'         => 'acme\myBundle\Entity\UserTask',
                    'query_builder' => function ($repository) { return $repository->createQueryBuilder('p')->orderBy('p.name', 'ASC'); },
                ))
