Symbol Changer: Change symbol type from one symbol to another
Allow change of symbol type from existing symbol on display

The ability to directly change from one symbol type to another will be included in PI Coresight 2016 R2. This includes the ability to not only switch between the standard PI Coresight symbols but includes switching between custom symbols added to the system by 3rd parties.
Thanks you for providing your feedback and helping us add the features you want to PI Coresight.
