At the moment it's not really possible.

I have the project to create a true non-global error object so that we 
can do:

Catch <variable>

   Print <variable>.Text;; <variable>.Code
   ...

If I succeed, it will be possible to add some user property to this 
object (a tag for example), so that you can add your own information to 
the error.
