Sage specific folder on Kobo for import from Calibre

How should I set KoboTouchExtended plugin in Calibre so that generated kepubs would end up in a specific folder on Kobo?
- by default they go to /Volumes/KOBOeReader/<author sort>
- I would like it to be something like /Volumes/KOBOeReader/.kobo/Books
- similar to /Volumes/KOBOeReader/.kobo/dropbox and /Volumes/KOBOeReader/.kobo/google_drive
