Hi Creative business unit III or Yoshi-P

I am writing this thread to asking whether if it's possible to have all the other main city Aetheryte have the world transfer function (Foundation, Kugane, Crystarium and Old Sharlayan) in 7.x or beyond? Also is there a reason for only the current 3 main cities (Ul'dah, Gridania and Limsa Lominsa) to have the world transfer function only? The reason I'm asking whether the other main cities can have this added feature is because I believe it can make it more convenient for players to transfer between worlds in a data center. If it's not possible due to T&C or policies then, please disregard this message.

Thank you for reading
