Automatic buttons

Hi, I have a question. Every week I have to create some reports in Excel and then I convert them into PDF, creating an dossier (230 pages). After I create the dossier I attach a Table of Contents which have some buttons to go directly to the chapters to avoid scrolling down. It is any way to make the buttons on table of contents automatically? The dossier have the same number of pages and the same chapters every week. But it takes too much time to add everytime the needed buttons. Maybe you can advise me to make my life easier. 

Thank you,

Costin
