Game Time Card also count as Crysta (or just Square Enix Gift Card)

Have no idea where to put this, simple request to allow the game time card to be either 'time' or translate into some sort of crysta equivalent.

Sometimes I get gift cards for battle.net (blizzard), steam, xbox, playstation, or whatever as gifts- which I can use on almost anything.

Here you've only the game time card.

So- It would be handy if the card was also allowed to be Crysta, or (less importantly but perhaps interestingly) just a Square Enix card. So you could buy whatever games from the SE store, subscribe to FFXI, FFXIV, or make cash shop purchases.

Not an earth shattering issue but occasionally I get cards as gifts cause I'll usually have already bought the specific things I'm directly interested in myself, yet I don't really get these (FF) type of cards because their use case is quite limited.

Thanks for reading~
