Referencing fixtures respectively

[brukrneti]

Okey, say we have this scenario: we have 2 entities, Building & BuildingTranslation. Every Building has translations in 3 languages. So 5 Buildings = 15 BuildingTranslation entries in database.
So what I basically want to do is to assign buildings to BuildingTranslation respectively.
I've tried multiple ways of doing it but couldn't make it work so I found a workaround:

App\Entity\Building:
    building_{1..5}:
        street_name: <streetName()>
        street_number: <buildingNumber()>

App\Entity\BuildingTranslation:
  building_translation_{1..5}:
    title: <company()>
    translatable_id: '@building_entity_<current()>'
    locale: 'en'

  building_translation_{6..10}:
    title: <company()>
    translatable_id: '@building_entity_<($current-5)>'
    locale: 'de'

  building_translation_{11..15}:
    title: <company()>
    translatable_id: '@building_entity_<($current-10)>'
    locale: 'fr'

You can see that I calculated referencing entity manually with building_entity<($current-X)>

Is there any other way to make this work? It would be really great to have a feature to loop through the referencing fixtures from the first to the last. Hopefully this will help someone out, at least.
