[otrs] How to add a new field to Agent's profile?

Hi there. What's the correct way to add a new field (JabberUID) in the Agent's profile so we can configure our Agents to receive notifications on email and Jabber? I'm thinking on setting up a Ticket Event to make it send these Jabber notifications when a Ticket reaches its EscalationTime. Is there any way to create a new ArticleType (I.E: xmpp-notification) so I can create an Notification Event and use it to notify my Agents via Jabber instead of creating a Ticket Event?
