Symfony and Doctrine. How to connect 2 different child entities of the same class in a selection?

Question

symfony

Good afternoon.
I have a base entity - Place and 2 of its children - InPlace and OutPlace
Accordingly , InPlace and OutPlace are inherited from Place .
There is also a geo object class - Geo

class Geo{

  /**
   * @ORM\ManyToOne(targetEntity="Base\Place", inversedBy="geo")
   * @ORM\JoinColumn(name="place_id", referencedColumnName="geo_id", onDelete="CASCADE")
   */
  protected $place;

}

As you can see, it can have both InPlace and OutPlace , and that's why I bind using the Place
base class. Actually, the question is - I make a selection from the database, for example, like this (Geo repository)

$qb = $em->createQueryBuilder('geo');
    $qb
      ->select('geo')
      ->leftJoin('geo.place', 'place')
      // поля photo есть только в дочерних классах. В Place их нет
      ->leftJoin('place.photo', 'photo')
    ;

and I get the corresponding error that there is no photo field in the Place class (it is correct, because photo is only in child classes). How can I make it so that when fetching, not the base class is picked up, but the child class that is attached to this Geo ? I dug in the direction of resolve_target_entity , but there the binding goes one class to one
