Sony calibre drivers etc. are the best at collections probably because they have been around a long time
The Tweak
Specify how SONY collections are sorted gives lots of options.
sony_collection_sorting_rules = [(['author_sort'], 'series_index')]
will sort your series collections automatically.
I use a plugboard as well because I like to see the series name and number.
{authors}{series:| - | }{series_index:0>2s}
destination authors
gives author name series name series number in the author field where the text is smaller so it displays well. Thanks to Jackie_w
