The ability to turn a regular ironman into a regular group ironman account

[Iron Zyzz]

since there is the ability to de-iron an ironman account, which is essentially making a restricted account less restricted, I think it would make sense for there to be an ironman to group ironman transition (but not vice versa) since a group ironman account is in a sense less restricted than a normal ironman. It is something I have seen being wanted by quite a few people, including myself.
