Campaign in which a user can only redeem 1 code from the campaign?

[ker0sec]

More of a feature request. It would be nice if you can make a campaign in which only one code from said campaign can be ushered by a user. Say you want a user to be able to use either a 25% off code or a flat $10 off code but they will have to choose 1 or the other and cannot use both.

If it is not possible now I think it would be a great addition.
