Conditional Formatting

Hey

I need to add a criteria to one of my conditional formats. At the moment I have used up all 3 conditions to show different cell colors.

Review = Red
Send = Yellow
Dispose = Green

What I would like to do is add a second criteria to flash up green. At the moment my conditional formatting shows

cell vale equal to " Dispose" is green, can I add a second text "Dispose - Negative" to the third line of conditioning. I need it to show up in green so i dont need more than 3 conditions per se just add a criteria to my third condition. Can this be done?

Any help much appreciated.

Gareth.
