Hi!

I often need to add audio files to narrate my pages in my EPUB. The audio files are nicely named according to the page number they narrate.

Currently I have to manually choose the corresponding audio file for each page. However, it would be nice to be able to automatically determine the audio file from the page number.

I know this is possible with a smart object, or JavaScript, but these are not allowed on most platforms.

Is there any way to achieve this?
