This was a Sphere feature that was incredibly useful and I am disappointed that it is not in TR. Say we have a sponsor for our event. Part of their package is we offer them 5 complimentary registrations. It is easy to CREATE the discount, but to add it in the URL? Why make the code? There should just be a field when anyone goes through the registration process that they can enter the discount code. I am a fundraiser, not a computer programmer.
