RStudio, knitr, pandoc, Word: how do I get a 'new page' in my docx?

I am using the RStudio, knitr, pandoc, MS Word combo to get my final results in a docx document.

Occasionally, I would like the report to continue on a new page. I can't find the way to achieve this.

From what I have Googled, it seems to be possible with CSS. I don't know HTML or CSS, but if it is the solution I will learn. Just don't want to take the wrong road...
