That option has always been there, it hasn't been recently added. Also, the Mogstation is not region specific, what makes it region specific is the account information from
https://secure.square-enix.com/account that has been tied to it when you created a FF14 account. Besides you have multiple ways of paying atm including debit, which are options the european community can't use, so I doubt you will get timecards, considering you just got Crysta cards as well.
Also, I doubt you will get a developer response on it as it is more up to the executives. it sucks for the rewards, but alas, you have to work with what you got.
