I am currently doing work for a client who insists on having 2 separate tables of contents. One being the normal kind where it shows the entries of the client's work in the order they appear, and then a second one where entries are grouped by themes. So it is kind of like an index but not, since an index auto-generates based on presence of keywords. So the question I have is, when Publisher generates a Table of Contents, is there a feature or tool I can use to rearrange the order of entries and break them up into subgroups (they need subheadings of the themes)? I note that currently if I manually try to change things, it reverts to the auto-generated state as soon as I hit "Update Table of Contents". If worst comes to worst, after absolutely ensuring that the rest of the book is "set in stone" so to speak and I am absolutely sure the page numbers will not be affected, I suppose I can just copy the text in the table of contents and mess around with it. Any thoughts on the best way to go about this would be greatly appreciated. Thank you for reading!
