Hello, I am trying to determine the best design for associating a character and a dedicated server. when a playfab user picks a server to login to, i would like to check if that user has a character for that server or need one to be created. the intention is that a user will only have 0 or 1 characters on a server. so the question is identifying the server and asking playfab if the user has a character that belongs on that server. this is making the assumption that all my player info will be stored on playfab including the characters that exist on a server. is there a best practice design for this? my first attempt was to save server id into character data, but it seems that is not ideal for searching.
