@mlaggner Thanks a lot it works perfectly.
I wanted to organize my movies by saga and by the first letter of the saga or of the movie if not.
If it could help someone here is my code for the renamer :
${if movie.movieSet.title} ${movie.movieSet.titleSortable;first} ${else} ${movie.titleSortable;first} ${end} ${\,movieSet.title,}
