Make "Issue Date" autopopulated or required on Attachment form

Is there a solution to either make the "Issue Date" field on the business process document attachment form required and/or autopopulated?  We want to enforce users to supply a value to know the date when the attachments have been uploaded into the BP record.  Setting these properties on the uDesigner (Document Manager --> Document and Folder Attributes --> Document Properties) only has the effect of making the field autopopulated and required on the document properties when opened in the Document Manager.  Just checking to see if anyone has come up with a solution for this.

Thanks -
