fontawesome in dropdown menu items

I wanted to have fa icons in dropdown menus so I wanted to be able to id each item, so I edited includes/devdmbootstrap_enhanced_nav_walker.php line 63:
$atts['class'] = 'dropdown-item';
and replaced it with
$atts['class'] = 'dropdown-item dropdown-item-' . $item->ID;
Now I can add fontawesome in css with something like

ul.navbar-nav li.menu-item div.dropdown-menu a.dropdown-item-147:before {
  content: '\f028';
  font-weight: 900;
}

This would be a nice addition to a future release.
