Auto release on shutdown

Does anybody know if there's a way to get the Whole Hog III to automatically release all cues on shutdown? When you shut down the board, at least on our system, all the lights stay up with whatever values they had from the last used cue. They will stay on until we restart the system, which is just kind of a pain sometimes. I know it's possible to program in a startup macro - is there an option for a shutdown macro as well?
