When using Shape.UniqueID to set a shape's GUID after it is dropped,
there is also the option for this parameter: visGetOrMakeGUIDWithUndo
It says this option is:
"Undoable."
https://docs.microsoft.com/en-us/office/vba/api/visio.shape.uniqueid
But what does this actually mean in terms of behavior setting UniqueID this way?
