Like to add in Opportunity List window (Table) under Process/Stage and in Dash Board Filter to be able to specify by an Opportunity field.
Example select a field called reference that has a code "Mailer01" This way you can in Dash board Filter by fields and the type to see how much was sold or forecasted by mailer campaign. Also have the same added selection under Stage so you can list what you want to export / view not having to go through report or selecting those records and omit them in the list view.
Thanks,
JM
