There is a way for order books by
- author
--- title
------- Tags

For example, with Ant Movie catalog (Dispaly - Sort by - Advanced) opens a window where you I can decide which order will see the movie, and you can put as first the year, as second the director, etc. etc.
I would do the same thing with Calibre, is possible?

Thanks and sorry for my bad english
