Yes, open the overall_header.html file within the style you are using. Do a text search for "<a" and it will cycle through the links in the file. The majority of the links in the overall header are for the main menu.

Once you add the link you then need to go into your acp -> styles -> templates -> cache -> find the "overall_header.html" on the list -> check and delete it

Next time you load the page it should have the updated overall_header
