When someone signs up for a subscription plan, rather than having it start immediately or on a specific date for all people, have it start when that person's current plan ends. Or allow me to set the start date for each client as they sign up. I currently use my website to pull in new clients but I'd like to sign them up with subscriptions after they have trained with me for a month. When they start their plan will be different from when they pay and I would like more control over that.
