Not explicitly but depending on the situation canny orders, waypointing and cover arc can approximate S & S.
The way to do it is keep your squad still (if they move there's more chance of being spotted), with a cover arc then if you see action coming set a 'move' or 'run' order with multiple pauses so that at the end of the 60 sec move they'll be hossing it out of trouble. If nothing happens reset it again.
