How do I create a Bind in COD4 (PC)?

basiiicalllyyy, i play promod servers and want to change the colour of the kill-feed. i know how to do this:





[go into console] /G_temcolor_allies 0 1 0 1





however, I don't want to type this every time i want to change the color, can i not bind it to something??





THANKKSSS :)
