We use tags for this. Each user has a user Id and so when the device registers with azure, you add their user Id as a tag to the registration.

protected override void OnRegistered(Context context, string registrationId) {

    ...

    var tags = new List<string>() { "userId4" }; // Your UserId here

    ...

}
