setting the computer to 2000


i'm not much with algebraic notation (as in source and analysis etc.). so, usually i just play a position out against the computer. i always try to set it at 2000 to give me a reasonable set of moves to look at. however if it's the computers' turn (at the first move), it defaults to 1200 and i can't change it to 2000 before it makes it's first move. does anybody know a way to permanently set the computer at 2000 so i can avoid all this? thank you
