BOGO options?

I am trying to setup a simple rule. When someone buys 2 tickets, they get 2 free. I am not seeing anywhere to set a minimum ticket purchase like for example "4 tickets" so that I could use discounts to automatically apply the discounted rate.
If I set up a coupon code, what is to stop people from trying to use it on other ticket purchases?
I could set up a ticket type that is the total discounted price for 4 tickets, but that would result in only 1 ticket / qr code.
I need 4 tickets / 4 qr codes

Any solutions for this?

Hi Jeff

I'm afraid of the extension does not support this feature. When you say buy 2 tickets, is it the same ticket or different ticket?

Maybe you can send me link to registration form so that I can understand your request better?
