[xwiki-users] Livetable counter or unique id?

Hello, I am a new user of XWiki and am just starting to explore its functionality. I've searched for an answer this question but haven't found anything yet. I have created an application (which allows me to record details of requests received from other parts of my organisation), and have entries displayed in a livetable. Is there a way of adding a counter or unique ID field to the application and livetable display? This would make it much easier to refer back and find entries. I can't see a "doc." property that would enable me to do this. Many thanks in advance for any assistance.
