After some tinkering, I realized that you could a modification to the first-child selector to call out the specific link. In this code below, our "Emergency Contact" link was the second link header (the first "li" item after the first-child selector). If your link header is the third or fourth in the Quicklaunch, all you need to do is add a subsequent "+li" or "+li +li" to select the applicable link.
/***Single Link Header Customization***/
.menu-vertical > ul.root > li.static:first-child +li {
font-weight: bold;
padding:1px 1px 1px 0px!important;
color:red!important;
}
/***End Single Link Header Customization***/
Hope this helps someone out there.
