Selectable Content Types for Author Taxonomy

I'm using Author Taxonomy in an own content type ("magazin article"). Currently the author and the date should only appear within the content of this type. Later, it's planned to extend this to other content types. Therefore I have created a category named "Authors" which only belongs to the type "magazine article"). Thus the author's name doesn't show up on nodes of another content type, but - and that's the issue - the date does. Okay, I know it is possible to include a code snippet print author_taxonomy_output($node); into the node.tpl.php file. But it would be much more comfortable to have check boxes for each content type in the configuration of Author Taxonomy where one can select in which content type(s) the author's name and date stamp will appear.
