I have an InDesign CC 2015 document where the TOC has been automatically generated by InDesign based on paragraph styles applied throughout the document. In addition, I've used the hyperlink destinations created by that process to make navigation buttons on each page. However, when I update the TOC, all the buttons default back to the same destination (Since "Appendix" is the destination all the buttons go back to, I think it assigns the default destination as the first one that would appear in an alphabetical list.) Any idea how I can update the TOC without breaking all the buttons. Should I be using a different method to create the buttons? Any help would be appreciated.
