hardcoded links

Is there a way to have the carousel items link to a page on the site without having to hard code the whole address? When I tried /page_id=xx thinking that it would point to the root URL and then that page, it did not work. The only way i can get it to link to a page is to input the entire URL, which would make and future edits to the site problematic. Thanks
