Org-export: Change position of author and title in the tex-file?

Question

I want to convert my latex template to an org-mode template. I want to change where the \title{} and the \author commands are inserted in the tex-file. At the moment these commands gets inserted just before \begin{document}, but I want to use these variables in my preamble to add the title to the header of each page. In my ~/.emacs.d/init.el I have made a custom org-latex-classes which looks like this.

I have tested the Latex-part of this problem and compiled the tex-file where I moved the \date, \author and \title commands where I wanted and it worked like intended.

I have tried #+LATEX_HEADER_EXTRA: \title{some title} \author{me} and removing the #+TITLE: and #+AUTHOR from the org-file. This has the effect that near \begin{document} org-mode persist keeping the \title{} and \author{} but empty, but the one written in #+LATEX_HEADER_EXTRA gets inserted where I wanted it to be.

(add-to-list 'org-latex-classes
    '("myreport"
      "\\documentclass{report}
       \\usepackage{graphicx}
       ...
       [NO-PACKAGES]
       [NO-DEFAULT-PACKAGES]
       [EXTRA]
       ;; Insert \date \author \title here
       \\makeatletter
       \\let\\newtitle\\@title
       \\let\\newauthor\\@author
       \\let\\newdate\\@date
       \\makeatother
       ..."
        ("\\chapter{%s}" . "\\chapter*{%s}")
        ("\\section{%s}" . "\\section*{%s}")           
        ("\\subsection{%s}" . "\\subsection*{%s}")
        ("\\subsubsection{%s}" . "\\subsubsection*{%s}")
        ("\\paragraph{%s}" . "\\paragraph*{%s}")
        ("\\subparagraph{%s}" . "\\subparagraph*{%s}")
    )))

I want the \date{}, \author{} and \title{} to be inserted where the [EXTRA] is placed instead of the bottom just before \begin{document}

I have looked around for answer to this question but found nothing, so if the question is already answered please show me where.
