Promo Codes- allow promo codes to be used only for specific classes or events Merged

What specific challenge or problem does this idea solve?

Promo codes currently can be used for ANYTHING. I would like to create promo codes only for specific classes or events.

How should this work?

Who will benefit (Admins, Staff, Students)?

business and students

How will this change impact your daily tasks or overall experience?

People who don't register for the correct class get to use the promo code discount for something which it is not intended.
