Sorry that code did not come through right. This is what I’ve tried:
[wp_show_posts id="93" settings="category__and=style&tag__in=homepage"]
[wp_show_posts id="93" settings="category__and=8&tag__in=68"]
[wp_show_posts id="93" settings="category__and=style"]
[wp_show_posts id="93" settings="tag__in=68"]
