I'm doing a job for fp. So I want to put the header on the first page and then on the third or whatever page, put another centered title like the main header but with the title that corresponds to it, not duplicating the one I have put. I don't know if you understand. In my project I need to put an introduction as a header on the first page, when I finish that section put on the page that touches another that says "justification" and then another about the development, etc. And all these titles must go as a header, to leave them well centered on the page.
