How to right-align signatures on newlfm

Question

I'm trying to use the newlfm class to write a letter, but I've run into this problem.

It's customary in some places to have the signature aligned on the right side, as on stdletter, but everything before that including the closing line on the left. So far it has been impossible to do that with newlfm.

\documentclass[stdletter]{newlfm}
\closeline{This should be left-aligned}
\namefrom{This should be right-aligned}
\begin{document}
\begin{newlfm}
\end{newlfm}
\end{document}

Is there any way to achieve that on this class?

Answer 1

EDITED for better solution. Based on what I learned from my earlier post, I realized that if both the \closeline and \namefrom were being stuffed into the same box, then I could force the box width to be \textwidth without modifying the underlying class. I do this by putting the \namefrom into a box of width \textwidth, and just make sure it is right aligned.

\documentclass[stdletter]{newlfm}
\closeline{This should be left-aligned}
\namefrom{\makebox[\textwidth][r]{This should be right-aligned}}
\begin{document}
\begin{newlfm}
Testing
\end{newlfm}
\end{document}
