function register_tag_styles() {
    wp_register_style( 'tag-circulair-template', get_stylesheet_directory_uri() . '/layout-circulair.css' );
	wp_register_style( 'tag-circulair-kantoor-template', get_stylesheet_directory_uri() . '/layout-circulair.css' );
	}
add_action( 'wp_enqueue_scripts', 'register_tag_styles' );



This code does the trick for me, but i think it's to complicated when i have more than 10 tags with different stylesheets.....
