Adding a new field to the title page in beamer

I just read a question about adding a new field to a title page in beamer (Is there a way to add a field to the title page in beamer?). I have exactly the same question, and the proposed answer is efficient. However, it doesn't provide a method to define a new field.

Let's say I want to add a \supervisor field to a lot of presentations, with a specific color and font. I would like not to do so in the \author field each time.

I tried to alter \defbeamertemplate*{title page}{default}[1][] in beamerinnerthemedefault.sty, unsuccessfully (my skills are limited for such alterations).

Is there a way to add a new field to the title page?

PS : I know I should have commented the original post for such a question, however I don't have enough reputation to do so. That's why I created a new thread.

You can easily add text before or after the tile page elements via

\addtobeamertemplate{title page}{before material}{after material}


Thus you can put your supervisor's name at towards the bottom of the title page via

\addtobeamertemplate{title page}{}{\begin{center}Supervisor\end{center}}


\documentclass{beamer}

\begin{document}

\title{Talk title}
\author{The author}


If you need to place the material in a different order between standard elements then you will need to modify the template from beamerinnerthemeXXX.sty where XXX is either default or the particular inner theme you are using.
