Hey, so after playing around with it on http://www.abcdinamo.com/specimen/olicLd
I found out they use the css:
Ok so what you can do is create a textformat that uses the font.
Each textformat has a "HTML class"

Here it is "_Default" for example.
Ok now go to "Lay Options" -> "Custom CSS & HTML" and in "Custom <head> content" put:
<style> ._Default{ font-feature-settings: "ss09"; } </style>Of course instead of _Default, there should be the html class of your textformat.
