[Calibre/Kobo] Send some format (pdf, cbz) in specific folder?

[jedineofr]

Hello

(I hope I'm posting in the right topic)

I use Calibre for my entire library (epub, pdf, cbz).
On my KOBO Clara HD, I use Nickel for the epub and KOReader for the "specific" files (example pdf and cbz).
Right now, I'm going through "Save As" > "Save One Format" > "CBZ". I lose the information if the book is well synchronized with the Kobo

I would like the "specific" formats to be sent without conversion to a specific folder (for my part: ".specific_files" at the root of my Kobo). This folder is used as Home when I switch to KOReader.

Is there a way for Calibre to transfer specific formats to a folder?

Thank you in advance for your answer.
