Change Weather in a mission?

I've had a blast racing Mustangs at the virtual Reno Air Races, but now it is time to make the weather more realistic. Can I change the winds in either of the Reno Racing Missions? How about changing weather in the Reno Air Race multiplayer setup? My weather link is disabled when I try to change winds in a mission or in the multi-player mode.
Can I save a mission under a new name and then change weather?
I'd sure like to get a good crosswind from the southwest blowing for the unlimited race to make the thing more realistic. Any suggestions appreciated.
