DocumentId Issue with MyWebMethods

Hi,
For purposes of filtering we are setting the DocumentId for Publishable Documents using the “watt.server.auditDocIdField” to a Business Specific Unique value. This value shows up in MyWebMethods when viewing the logged documents and we are able to filter on the same.

However, when a document is re-submitted the same Document Id appears for the newer version of the document and when we try to click on the older version it shows the data for the new version.

Is there a way to change the Document ID when a Re-Submit is done so that uniqueness is maintained and we would be able to see each version of the document.
