Adding multiple audio files at once

In Presenter it is possible to drop one sound file that has all of the narration in using tthe Audio Editor.  From there I would place tthe sound where needed in the project.  Is that possible in Storyline?  It looks like I can only add sound to one screen at a time and also to save the entire audio file for the project looks like I have to save the files one at a time.  Is there a quick fix for this?
