We have memberships that are discounted based on age for example our senior memberships start at age 55. When the person reaches 55 I would love the ability to set up a senior membership to begin on or after the birthday so there is no interruption in membership or need to refund and recharge. Right now the system won't let me add a senior membership to begin the day after the members birthday because they are not 55 on the day that I am trying to add the membership.
