I don't find if it's possible to put a book in multiple series in calibre.
want to class it chronogically (in the universe) and also by the series book.
Example : "Star wars jedi genesis" on "star wars jedi genesis" and also on "before republic"
I know I can make a custom column, but i prefer, if it's possible, to make it with the series directly.
I try to put a & or a , but nothing...
thanks for your help!
