Is there a way to `\includeonly` when the memoir document is monolithic?

Question

When writing a memoir document it's easy to focus on just one chapter by using \includeonly.

\documentclass{memoir}
\title{title}
\author{author}

\includeonly{chap-3}
\begin{document}
\include{chap-0}
\mainmatter
\include{chap-1}
\include{chap-2}
\include{chap-3}
\end{document}

But when using memoir through org-mode on Emacs

#+title: title
#+author: author
#+LATEX_CLASS: memoir

#+INCLUDE: "chap-0.org"
#+LATEX_HEADER: \mainmatter
#+INCLUDE: "chap-1.org"
#+INCLUDE: "chap-2.org"
#+INCLUDE: "chap-3.org"

the document becomes monolithic and it is no longer possible to use \includeonly.

#+LaTeX_HEADER: \includeonly{chap-3}

Is there a way to \includeonly when the memoir document is monolithic?

Two more issues would be nice, but I'm not hopeful either is possible, because I believe they cannot be done directly from LaTeX.

1. Disable the output of the title page and preface.
2. Number what's being include-ded-only from page number 1, for convenient use as an independent handout.

If none of these questions has an answer, I'm quite content with editing the text by hand to make an individual chapter an independent article, but that doesn't fly with memoir because, like koma-script, only the book type is supported, and this requires maintaining an additional style that mimics what's done under memoir.

Edit:

Alternative way of asking the question

After writing a memoir manuscript, how can I produce a PDF document of just one chapter formatted as an independent article?
