Third check option on won/created

Amazing job you keep doing cg and staff team!

A suggestion if i'm allowed (not sure if was already suggested though)

Could you add a third option check in the GA won/created so those people who win can check the GA as Claimed, then creator click the Sent and person who win click as Received.

That way those KEYS are not compromise for the GA because a winner who already saw the key could already activate it and marked as not received (claiming he/she already won the game, meantime give the key to a second friend who activate it therefore keys are duplicated and GA creator needs to deliver a new copy, resulting in an unfair situation for the creator).
Doing this, creator won't click the Sent until the winner check as Claimed. This of course won't stop greedy people from trying to cheat the system, but at least will make a little harder to get away with it and it will give one more tool for creator of GA so they get less cheated in some cases.

Again, thanks for the amazing new feature and waiting for more to come! ;)
