LOBBYMANAGER: Setting the spawn prefab index, prior to OnLobbyServerCreateGamePlayer

I have a found a couple of topics on this, but no one is addressing my particular issue.

Essentially, I have the system working pretty well, I have updated the Network Lobby from the asset store, to include my buttons for selecting the player character. I set the prefab index from those buttons in this script which is applied to the LobbyManager object:

Code (CSharp):

1. public class NetworkLobbyHook : LobbyHook
2. {
3.     public short p_index;
4.  
5.     public override void OnLobbyServerSceneLoadedForPlayer(NetworkManager manager, GameObject lobbyPlayer, GameObject gamePlayer)
6.     {
7.         LobbyManager nlm = NetworkLobbyManager.singleton.GetComponent<LobbyManager> ();
8.         Debug.Log ("Before LobbyManager playerPrefabIndex = " + nlm.playerPrefabIndex);
9.         nlm.playerPrefabIndex = p_index;
10.         Debug.Log ("After LobbyManager playerPrefabIndex = " + nlm.playerPrefabIndex);
11.  
12.     }
13.  
14.     public void chooseRedBoy ()    {p_index = 2;}
15.     public void chooseRedGirl (){p_index = 3;}
16.     public void chooseBlueBoy (){p_index = 4;}
17.     public void chooseBlueGirl (){p_index = 5;}
18.     public void chooseYellowBoy (){    p_index = 6;}
19.     public void chooseYellowGirl (){p_index = 7;}
20.  
21. }

and in LobbyManager:

Code (CSharp):

1.  
2. public short playerPrefabIndex;
3. public override GameObject OnLobbyServerCreateGamePlayer(NetworkConnection conn, short playerControllerId)
4.         {
5.             Debug.Log ("CreateGamePLayer = " + playerPrefabIndex);
6.             GameObject _temp = (GameObject)GameObject.Instantiate(spawnPrefabs[playerPrefabIndex], startPositions[conn.connectionId].position, Quaternion.identity);
7.             NetworkServer.AddPlayerForConnection(conn, _temp, playerControllerId);
8.             return _temp;
9.         }

My issue is that the setting of my prefab index happens after the lobby has created the game player. My output log looks like this:

CreateGamePLayer = 2 (default value)
Before LobbyManager playerPrefabIndex = 2
After LobbyManager playerPrefabIndex = 7 ( value set from the button)

How can I set the index prior to the server creating the game player?

 

Is there a suggested approach to do this? I'm fine if how I'm going about this is wrong, I'm really in limbo until I can get past this.
