Individual Page Header Link

I have split up my website into three sections using custom header and menu plugins to make three “homepages”. The first header is set as the default and the other two are changed per page using the Unique Headers plugin. The problem is when you click on any of the headers it returns you to the default header homepage (like it was designed to do). I need to be able to change the pages with the custom headers to return to different pages and not the default.

Any ideas/plugins?

FYI: I also have no way to upload a custom template page (no access to wp-content).
