I'm not sure exactly how to ask this, but here goes: I have a jailbroken kindle Oasis that uses KOReader. I set my KOReader home directory to a folder named "EPUB_PDF", and this is where calibre sends my books when I use wireless transfer. After I transfer a book, it shows up as "On Device" in calibre, which I would expect. To keep my books organized on my kindle, I have several subfolders under EPUB_PDF (Author, Series, etc.). After I transfer the books onto my kindle, I move them into the appropriate subfolder. The book will still read as "On Device" until the the next time I connect to calibre, at which time it's not still "On Device" anymore. Is there a way to configure calibre to recognize these subfolders?
