How can I include the GUID of a diagram in the Diagram Info Pane?

Hello, I want to add the GUID into the Diagram Info Pane of my models in MagicDraw.

I know I can customize the information included in the Diagram Info Pane, but the GUID doesn't auto-populate the way I expected. How can I tell MagicDraw to include the GUID in the diagram info pane?
