During troubleshooting scenarios we periodically need to save a problematic PDF file as a PS file to regenerate it with the distiller. As a result, the bookmarks are lost. We would like to see an option to export bookmarks from a problem PDF file and be able to import them into a working PDF file. We understand there are 3rd party solutions that can achieve this but we work with highly sensitive data and would prefer an Acrobat native solution that would be available in Acrobat 2017 Classic and Acrobat DC.
