Importing audio files

Is there a way to import an audio track? I arrange percussion charts for marching band as well as concert, and sometimes I don’t have access to an xml in order to import the wind parts. It would helpful to be able to write to the mp3 or wav file.

The only way (so far) has been to attach the audio to a (dummy) video file and attach the video.

Great idea for a workaround, thanks. Although I hope this could be implemented in the future.
