3D FlipBook - Add books to Global Wordpress Category/Tag

Hey! Thanks for this amazing plugin.

I want to ask is there a way we can add the books to the global Wordpress categories that we have available on our website or the global tags. This is because we need to show the flip books in our Flatsome Theme slider section, but while querying for the flip book categories, it does not seem to be picking the categories made by flipbooks. Is there a way we can add flip books to the default Wordpress taxonomies instead of the custom flip books category ?

Much appreciated
