Expiry Date alert for Documents

Hi All,

We maintain a lot of documents in Windchill that gets expired every year and has to be replaced with a new set fo documents or updated as per new standardization guide lines.

Currently to keep a track of time and the approaching expiry date, for a Windchill document, we use Excel. Is there an option in Windchill to track the expiry date of a document and may be alert the user before the date approaches? Something similar to the calendar alert functionality in MS Outlook.
