SDN findAll performance and populating entities at depth > 1

In my case I have originally some

class Entity {
    @Relationship(type = "PARENT", direction =  Relationship.Direction.INCOMING)
    List<Entity> children;
   @Relationship(type = "PARENT", direction =  Relationship.Direction.OUTGOING)
    Entity parent;
}

where I now want to limit this in both directions to 1-2 levels. So I want my projected entity to contain entities with all properties but no relationships.
So as I have to know the direction, I think there is no way to do this with the interface?
