So I have a PMPro Member and an Order. As part of their membership I need to allocate a Storage Location which is my Advanced Content Type. I can add the storage location as a relationship on the PMPro Member and/or the PMPro Order.
However, I wanted to be able to create the bidirectional relationship back. So when I view/edit the Storage Location I can view/edit the associated PMPro Member/Order. When I edit the Storage Location pod to create a relationship back to PMPro the only Relationship I can see is for the PMPRo Membership Level and not the Member or Order.
