How to add new line before *all tags* in html?

Does anyone know a trick to add new line before all tags (incl. html, jsp, jsf) in html files? It's annoying that by reformatting an html file, most of the tags that don't have new line before them remain the same way. In order to add new line before tags, we can use "Insert new line before" option and add individual tags in there. But I want all tags to have new line before them and it's impossible to insert all tags in this list.
