You may be able to put that command in your config file. I have a key on my keyboard with all my favorite commands bound to it. I use the minus key on my keypad. I think that is listed as MINUS_KP in the config. You can use any key you like though.
My favorite commands are: helpusobi 1 (enable cheats), g_saberautoaim 0, g_saberanimspeed 1.1 (speeds up the swings a little bit), g_speed 200 (to make the running slower).
So my bound command looks like this.
bind MINUS_KP "helpusobi 1; g_saberautoaim 0; g_saberanimspeed 1.1; g_speed 200"
