[Tex/LaTex] Small symbol next to section headers

Question

I am writing a school report which has to be evaluated by two different teachers.

I need to mark which sections each teacher should read. I guess I can make a small symbol next to the header to mark which teacher the specific section is written to.

How is this possible?

I guess I can do something like

\section{Milking the Cow}
\teacher{A}
Some text

or editing the section headers or something like that.

Answer 1

A margin symbol could be clearer and less intrusive:

\documentclass{article}
\usepackage{lipsum,xcolor}
\def\Smith{\rlap{\protect\makebox[-3cm]{\color{red}\S}}}
\def\Philips{\rlap{\protect\makebox[-3cm]{\color{red}$\Phi$}}}
\def\Omar{\rlap{\protect\makebox[-3cm]{\color{red}$\Omega$}}}
\begin{document}
\section{\Smith Lore ipsum}\lipsum[2]
\section{\Philips Nulla malesuada}\lipsum[3]
\section{\Omar Quisque ullamcorper}\lipsum[4]
\end{document}
