title: using hibernate envers with unique table
body: <p>I am starting a Java project with Hibernate and found interesting the way the Envers work, but I wonder if you can only have a table to store all changes to the system? I do not know if I'm asking something impossible.</p>
  <p>What I need are columns: user, action (insert / update ...), table name and field changed.</p>
  <p>I do not know if this can be done with Envers or if there is another way.</p>
