Export LaTeX command inside figure environment

[Thomas S. Dye]

Aloha all,

Is there a way to add an arbitrary LaTeX command between 
\begin{figure} ... \end{figure} during LaTeX export?  I want to 
end up with the following snippet, but can't figure out how to 
slip in \setfloatalignment{b}.  

\begin{figure}[htb]
\centering
\includegraphics[width=.9\linewidth]{hilbertcurves.pdf}
\caption[Hilbert curves]{\label{fig:orgparagraph1} Hilbert curves 
of various degrees \emph{n}.}
\setfloatalignment{b}
\end{figure}

All the best,
Tom
