How can I add a Noticeboard Item from an Incident?

One of our Incident Management lifecycles includes a "Declare Major Incident" action and downstream status/branches.  We would would like to have an action associated with this status that creates a new NoticeBoard item (of a special "Major Incidents" Noticeboard Category that are shown only to Analysts).  How should I accomplish this?  Do I need to drag the Noticeboard object into Incident?  Or can I trigger it some other way.  I'd particularly like to automatically paste a lot of the relevant information into the Noticeboard fields.

Thanks,

Charles
