You can actually edit all the missions, including the training ones !
 All you have to do is to open the *.wma files in your \Data\Missions in
 WordPad and tada ! you can edit all that you want.
 For example, edit the round time at the training missions so now I can
 get Gold Medal for free !!! (you also have to edit the option
 EndGameWhenTurnEnds or something like that)
