I use Calibre 2.76 and Kobo Aura 1.

I have a custom column on Calibre (let's say "Bookcase") of type text, but with a fixed list of allowed values.

I'd like to syncronize that column with the "Collections" column on the KA1 library, so that, for every book, the Collections column lists the same value from the Bookcase column.

I can't find an obvious way to do that. Can you help me?

Thanks.
