Audio Export dissapointment

This is a wonderful program, but it is disappointing that after so many years, there is still not a way to export audio as part of a file.

For a long time many eBook readers have supported embedded audio playback. It is possible to have a PDF file playback audio and webpages could playback audio forever. Yet here the premium book creation / editing software can import a zillion audio and video formats, but one cannot do anything creative with them.

Audio export within a file should have been made available a long time ago, even if a paid plugin. Until then one of the best possible uses for this software is going ignored, even though a whole lot of people have asked for it over and over again. IT is very sad.
