As you mention fanfic, are you using the FanFicFare plugin to download it? If so, it can do this sort of thing if the source site has the information.
Otherwise, I don't think there is an automatic way to do it. That would need a source for the information and how to extract it and apply it. Some sites will have it, but the standard metadata source plugins for downloading metadata cannot update custom columns. They can put this into the tags, but that is not what you want.
Having said that, a possibility is the Import List plugin. It can read a CSV file and set metadata for the books from that file. If you have the information elsewhere and can massage it into a CSV, this could work.
