FS2004 Adv vs FSX Missions HELP PLEASE!

Hi to all!Apologyze for my bad english. I love the fs adventures. I have created various adv for fs2002/2004. Maybe I have not studied well the new tool yet to create the missions, but I don't find it so Intuitive. For example, i need to insert in my mission only a simple istruction to listen a wav when the plane is at some miles to a vor, an ndb, or a waypoint. Does a simple way exist for insert all this in a mission?? Since If I must every time to create an area, the length, the width, etc etc, i think that I will abdicate. :-( :( Thanks in advance for the help that you can give me.Patrizio
