[otrs] Internal links in FAQ articles

Hi, Using FAQ module 1.5.4 here on OTRS 2.3.4 and wondering how to simply manage internal links to others FAQ articles ? Is there a way to integrate a link so this one will be usable for agents AND customers ? The best would be a relative link with the same query parameters for Agent or Customers and a common script ... because at the moment we need to provide a link different for customers access than the one used for agents when writing articles ... Thanks by advance for your answers. Laurent MINOST
