Hi,
I had around ~100 epub files on my E-Reader, before I switched to calibre + calibre-web.
I set up a syncing system, so my E-Reader (Kobo Clara HD) would synchronize books from my calibre-web database to the E-Reader.
Calibre-web automatically converts all epub files to kepub when synchronizing.
Now, there is one thing I want to have as a finishing touch;
Is it possible to move all the statistics and bookmarks from epub to kepub?
I've looked into the database in KoboReader.sqlite and I don't really understand how the columns in 'Bookmark' work and how the position of a highlight / annotation is set up.

Can anyone tell me how to move the annotations from my epub to kepub?
With kind regards,
