[otrs] FAQ article prior revisions

Hi, I'm using 2.0.1 Is there any way to see the previous revisions of FAQ articles? (In the same way you can see the full 'revisions' of a ticket's responses.) If not, is this information maintained in the database, but just not currently presented by the front-end implementation? It's often useful to be able to review (or even roll-back) the changes somebody has made, but currently the history only shows the dates changes were made... Thanks in advance, Rob.
