calibredb not acknowledging 'preferred input order'
This issue has come up in my attempts to batch import various books of mixed languages.
I have set 'OPF' files as the top preferred input format in the 'Behavior' configuration dialog. When I add a directory that has a single logical book with a valid opf file present, if an epub file is also present then some of the metadata is taken from the epub regardless if valid data was present in the 'OPF' file. Is there a way to force calibredb add to use the 'OPF' file exclusively? I know I can subsequently alter the data in the database but each call to calibredb is 'time' expensive and I would prefer to do it all at once.
