Currently with our customers who've purchased a membership, that 'lives' in a specific order, which makes it hard to report on the purchases they've made, or for member discounts to be applied to future bookings unless they flag it at the point of sale. If the membership lived in their customer profile somewhere (preferably with an expiry date), it could pull through to all their bookings and things wouldn't get missed, and it would make it much easier to report on their purchases.
