Use the Project - RFP - Milestone preferences to set up default RFP milestones (that is, projects of type RFP). These should be the milestones that you frequently use for your RFPs. Keep in mind, that these are just defaults that will appear in the Add Milestone dialog box when you go to add milestones to a RFP in the Projects-General - Info screen. You can also create custom milestones and assign due dates for any milestone from that screen.
