Is it possible to cache/externalize each frame in beamer?

My option for speeding up compilation is using includeonlyframes(*). So, I have in my preamble, just before the begin{document}:

includeonlyframes{title,working,also1,also2}% no spaces between labels!

and the frame I am working with has

begin{frame}[label=working]
...
end{frame}

Now, just this frame is compiled. When finished, I change the label to a definitive one (or none) and go on by putting the working label to the new frame.

I normally compile always the title frame (by using label=title) to have a minimum of one frame, and also other frames for reference (for that I use the also1, also2... labels).

You just need to comment/uncomment the includeonlyframes line to switch to compile the full presentation.
