This will require a SQL schema conversion. Change the default Episode.auto_split_title value to NULL; create Series.auto_split_titles which default is TRUE; change front-end Episode.auto_split_title column to tri-state toggle; in SQL conversion keep all Episode.auto_split_title values that are FALSE, but set all TRUE to NULL.
