I guess the synchronisation with Scrivener is meant to fulfil this role. For those who don’t have that, there are probably only workarounds at the moment:
Some time ago, I released an extension for LibreOffice that could generate various documents for the narrative from an .aeon file. However, I don’t know whether the file format has changed in the meantime. If this is the case, the extension may also be able to process an exported .csv file.
If you don’t use LibreOffice, there is an alternative: A Python script that generates the same in Markdown format (i.e. plain text files with marked headings).
It may look a bit complicated, but you can also create .docx documents from the Markdown files with the help of Pandoc.
