Doctrine: DQL query without specifying class fully qualified name (FQN)

Is there a way to write DQL queries without specifying the fully qualified name of the class?

Is there a way to create the following query:

return $this->getEntityManager()->createQuery(
    'SELECT i
     FROM Company\AccountingBundle\Entity\Invoice i
     WHERE i.id = :id'
)->setParameter('id', 1)
    ->getResult();

Like this :

use Company\AccountingBundle\Entity\Invoice;
....

return $this->getEntityManager()->createQuery(
    'SELECT i
     FROM Invoice i
     WHERE i.id = :id'
)->setParameter('id', 1)
    ->getResult();

Or something similar. I really would avoid to set the full FQN in the DQL.

But I didn't find any "setClass" or another method to do this.

EDIT FOR CONTEXT

In fact, it is a Symfony project and the query is inside in a Repository class. I have a Doctrine XML definition of the entity, an entity and the entity repository also defined in the XML, but I always need to explicitly define the FQN, Any ideas?
