Saving books to disk

[thomcuccureddu]

Hello everyone,
I'm trying to organize my collection of comics on calibre and my results are not yet satisfaying.

I'm trying to do something like that :

{serie} {Total amount of book in this serie} / {serie}{series_index}{title}/ {Title}

I don't know how to get this {Total amount of book in this serie} or if it is even possible.

I also have a lot of books that don't belong in a serie, so it would be nice to find a template that doesn't show any weird brackets (or other) when there is no serie.

Thank you all very much in advance
