Sorting series with interim books/novellas

[sevengali]

Hi,

Recently got my first Kobo, and immediately put KOReader on it - love it, thank you for the hard work.

Sorry for the title - I know "series sort" is somewhat controversial I have searched the forum and GitHub, for both series sort and my specific question below, and have subscribed to https://github.com/koreader/koreader/issues/8472

I largely solved this issue by configuring Calibre to sync to my Kobo like so

{series}/{series_index:0>3s} - {title}

This means you end with

Series/1 - Book One
Series/2 - Book Two

Which until just now I was perfectly content with.

A handful of my series have interim/novellas, i.e. book 1.1 and 1.2. I've just noticed period get sorted to be after number, so all of these books sort at the end of the folder after the main series is concluded.

Series/1 - Book One
Series/2 - Book Two
Series/3 - Book Three
Series/1.1 - Book One (novella one)
Series/1.2 - Book One (novella two)
Series/2.1 - Book Two (novella one)

Is there a more graceful way of handling this without bumping all the books up to whole numbers? Can I prioritize period on the sort algorithm to be before numbers?

Thank you.

I'm not sure I get it right, but try "Sort by name (natural sorting)".

Can't believe I missed trying that... Thank you!
