Hello, I have two products that subscribe to the same content. One is a one-month subscription, and the other is a one-year subscription. I would like to make it so that if a person has a one-month subscription and they purchase a one-year subscription, the one-year subscription will start when the current one-month subscription is set to renew. I tried doing this by putting both of them in the same renewal group and selecting "Last expiration date in the renewal group" for the start date calculation, but it did not work. Is there another way to do this? Thanks, Todd
