I kinda miss WoW's favorite mount option when I play this game

I guess FFXIV doesn't quite need it just yet, since each mount is unique and neat. But I kinda cringe every time I get Black Chocobo or the Mana Glider. Both are just given to you and not interesting. I'd like the option to remove them, so I have more room for prestige mounts, or my personal chocobo.
