Right now a member can only have one assigned trainer, and assigning a new one replaces the existing one. Some clubs have clients who train with two or more personal trainers every week and want both trainers assigned to that client.
This also affects the Trainer role, which can only view profiles of members assigned to them. At the moment the second coach can't open that client's profile.
Example use case: A client does sessions with two different PTs each week. The club wants both PTs to see the client's profile and have the client listed as one of their clients.
