You can now set the total number of universal promo codes available, in total and by event. For example, if you wish to have a promo code that applies across all events but limited to 100 total redemptions across all events, you would set "Total Number Available" to 100. If you wanted to limit those 100 total redemptions to be a maximum of 10 per event, you would set "Number Available Per Event" to 10. Leaving either field blank enables to promo code to be used as many times as possible.
As a reminder, you can set universal promo codes that apply to all events or you can set event-specific promo codes that apply to specific events only.
