Unlike other study tasks that you can set to repeat on a certain periodicity, promotion codes tasks cannot be repeated.
Across all tasks, the repeat functionality is meant to repeat the same “define” portion of your task. You can adjust, if required, the intro, who/where, and rules of the repeated task.
However, the codes in promotion codes (added in the define portion) will most likely need to change from one repeated promotion code task to another, particularly when the codes are used to link data in an external system. Each code has a “value.” Many promocodes may be only used once.
Therefore, we’ve made promo codes a template type that you can duplicate, but not one you can repeat.
