You could download the stylesheet, change the fonts (find + replace) in there and re-upload, this should do the trick.

<script>
$(document).ready(function() {
	$('[href*="beaverhero.com"]').attr('rel','nofollow');
});
</script>

Notes: This code will target all links that contain the word "beaverhero.com" in the link.

That works perfectly, thank you!

@tuanphan Is there a way to configure the script so that it only makes links to a certain root domain (for example amazon) no follow while the rest is dofollow?
