Chapter 1 What’s New for FortiOS 5.2.1 : Usability Enhancements : Dragging Objects Between Policies in the Policy List
  
Dragging Objects Between Policies in the Policy List
Objects can now be moved or copied from one policy to another in the policy list. This includes source and destination addresses, services, users, user groups, and security profiles. The default “none” object is also included.
Because of this change, a blank policy can now be created, with the configuration determined by dragging elements from other policies.
