@Ranulf; I don't think it is possible to have more than one selection. Trust me, I've tried it one too many times before.
As for adding those selections, I'm afraid that that wouldn't be possible either, Uzuri. Without the source code for the game (KovuLKD has taken it with him when he had left), nothing is able to be added or modified. All you can do is try and work with it, see if you could at least choose a selection that works best for you. c:
