How can I make a specific Heading Level Start on a New Page (article class) ? (Automatically, not \clearpage)

Question

I have a basic article class document with headings to four numbered levels.

I wish to force a new page for every 1.X level heading.

I have tried the following at the end of each and every 1.X section

\clearpage

This works, but is there a way to automate this?

Answer 1

This should work:

\usepackage{etoolbox}
\pretocmd{\subsection}{\clearpage}{}{}
