Tasking Order edit?

[WargamerScott]

I started fooling around with the mission editor the other day. I created what I thought to be a throw-away mission that actually developed into something interesting. Unfortunately, the tasking order I wrote no longer reflects what the mission has become. Is there a way to edit tasking?

Also,

I want OS to receive a radio message with updated intel. How do I do this? I tried a trigger set to destination, but since OS is placed randomly, this doesn't always work. Any way around this problem?

Finally, and OT, how can you change the volumn on the button popping sound? It's so loud, it sounds more like you're firing a gun than hitting a button!
