If you want to add a new square later in the game, you should probably include room for it from the beginning, initially deleting it and any other extra spaces you'll have to include in your FEN code with the minus sign. You can add the space later by putting a piece or an @ sign (representing an empty space) on it. But if you're actually playing the game, you would want to use Game Courier, not the Diagram Designer.
