Any way for pandoc to print numbered sections in plain text output?

Any way for pandoc to print numbered sections in plain text output?

Here is my LaTeX input:
\documentclass{article}
\begin{document}
\section{foo}
\section{bar}
\end{document}
I run the following command using pandoc 1.11.1:
pandoc -o test.txt -t plain -N test.tex
And here is what I get:
foo
===

bar
===
Is there a way to have the plain text sections and subsections numbered automatically?
