Hi, is there a dynamic/unique code generation available?

I saw some messages regarding this feature. Ultimately, each player (user) should get one-time reward code unique only to him, so that no one else will be able to re-use the code again. I see very easy implementation:

1. Player wins (achieve specific score)
2. Playzo webhook connects to our API backend
3. Backend responds with unique code according to our custom logic .. something like SAVE20-BFTU or even better USER_NAME-BIG30-59BF-BD58

Is something like this possible? If not what is the rough ETA? This would increase sales even more due to the very specific unique code personalization.

Thanks much!
