Is there a way to handle block commenters properly?

[huangzonghao]

Wondering if there is a decent way to handle the block commenters?

Like the one we have in latex:

\begin{comment}
contents
\end{comment}

So the desired behavior is when visual select the content and trigger the nerdcomment, it will automatically insert \begin{comment} above the paragraph and \end{comment} below the paragraph.
