Allow import of audio annotations/sound clips

I know regular text annotations aren't necessarily available unless you tie it in the data or use something like text boxes but it would be really beneficial to apply vocal annotations to the reporting, or allow the inclusion of sound clips. When I think bookmarks I personally think guided tour to tell a story. Imagine if there was a voice guiding them along as well in that journey. Text is great and all but it has no emotion or inflection like an actual voice.
