Upgrade StorageExtra Columns in Middle Column of Page with Citations
At the moment, if I have a Book Section, I can have the Title of the Section and the Author (Creator), but when I click to get extra columns, I cannot select the Book Title, it is not available as an option. Is there any chance of getting more columns in here to choose from as I have sections that are the same name in different books - i.e. Introduction or Conclusion. It would be much easier if I could see the main book as well.
