Being able to have audio fade in and out in NV3?

I was just playing around with Nero Vision 3, Make my own movie I believe... I figured out to fae in and fade out video files etc. but is there a way to fade in&out audio files as well? I know I can cut the file down and have it stop where I want, but I don't want to have the song just cut off. I'd like to have it fade out where I want and have the new song fade in where I want.

Thanks for any help.
