How to generate a 404 page URL?

[rafster]

Hi all, 

 

I'd like to setup a Google Analytics URL destination goal that's based on the 404 error page being served. 

 

I've realised that Prestashop doesn't generate a specific 404 URL when the visitor sees this error page. The URL just shows the destination, even if it's broken.  

 

Does anybody know if there's a way to have the 404 error page generate a specific 404 URL? 

That way I'd be able to add this destination URL to the goal.

 

Thanks in advance.
