How can I export or preserve my PDF export custom layouts for transfer?

I have created a bunch of PDF export custom layouts and I want to save them in case I need to re-install the app or import them to another computer. Is there a way to do that?

I have downloaded the newest update for Storyboard Pro 5 but am afraid of installing it as I have to un-install the older version of the app. I am not sure if my prefs and custom brushes and PDF layouts will be preserved.
