page link that you are on has it's own class. using the same menu more than once

Looking for a plug-in that would allow me to change the class of a link within a custom menu inside a widget are when I am residing on that page. For instance if I am on the “contact us” page I would like the link in the menu on the right hand side to be blue and underlined while the rest of the links maintain the default link styling. Here is the catch…. this menu is re-used on other pages as well so I can’t just add a class within the custom menu options when building that menu.

Is there a plug-in that anyone knows of that would get this done or does someone have a way to do this through some other programming.

Let me know if this makes sense as it is somewhat confusing.
