The step where you create an Introductory Offer in iTunes Connect allows you to select only 1 of 3 options: Pay as you go, Pay up front, and Free trial. If my app already has a free trial period set up, can I set up an Introductory offer that's configured as "Pay as you go" with a discounted price? I'm trying to ensure that a potential customer can get both the free trial, which is already configured, AND a discounted introductory price.
