I now use this plugboard courtesy of Jackie_W in this thread

Format: device_db
Device: any device
Source Template2: {series}{series_index:0>2s|| - }{title}
Destination Field2: title_sort
And this tweak from Chaley
# Specify how SONY collections are sorted
sony_collection_sorting_rules = [(['author_sort'], 'series_index')]
The template adds the series name to the author and is very easy to read.
It will quickly update all of your collections at once instead of having to send them all again (or it did for me and I only sent one book to test it
).
I could be wrong but the change seems to be only in the database on the device.
Not entirely perfect but close enough.
When I look at an author_sort collection (the only collections I want) the books are listed in series_index order. If I have more than one series per author, it will put all of the first books in each series, then all the second etc.
Much easier than my old way of looking at the author, locating the series, and going to that series collection.
