@Andys:
For Custom Columns, of course. Easy. Simply change table custom_columns in metadata.db for the specific Custom Column you wish to protect. Do this while Calibre is not running. See the attached example.
If you need a tool to do the edit, download the 'DB Browser for SQLite' tool from
http://sqlitebrowser.org/
Needless to say, be careful what you touch in metadata.db. If appropriate, practice first on a test library. Also, close the tool before running Calibre.
