I just got the idea, that the following might be possible.
If the link is called like with an additional value for the language like <%db_cgi_url%>/jump.cgi?ID=<%ID%>&<%URL_en%>
Like this you can use as many different URL as you like, as long as jump.pm know how to handle.
How much reprogramming would that be? Should I post that in the custom jobs section?
