title: (Jupyter Notebook) nbconvert PDF via LaTeX custom date and title format
body: <p>I am using Jupyter Notebook to write up reports very heavy in code and LaTeX. I wish to change the title, date, and the format of them. Precisely, I would like all the text to be in a smaller size, 12 to 14px at the largest. </p>
  
  <p>I've spent a few days unsuccessfully trying to create custom *.tplx files for nbconvert. Regardless of the file I use, the title and date remain unchanged. In fact, nothing seems to change when I use a custom .tplx. </p>
  
  <p>I have found a couple other people asking about this which is where I found the information about templates and how to call them when using nbconvert. Every complete solution involved exporting as a '.tex' then making the changes manually. This is unideal as I often create several documents a day and that would slow me down a lot as opposed to a one-time solution.</p>
  
  <p>Any suggestions?</p>
