so you should have a unique master for every shape (same but connection varies)....is that the case?
(a new master is created even if its a current shape with even the color change)
No, the problem is that the master is made up of a
"Text Callout" Shape
"Visual graphic" Shape
"Group" Shape
The Shape Data property is located on the group shape, the Connection Point is located on the Visual Graphic shape.
So if i remove the text callout, and the Group Shape. I have to add a new Shape Data to the visual graphic and that resets all the pin numbers in the document.
If i instead remove the Text callout, and the graphic. I can then draw new graphics in the Group shape shapesheet and insert a text field and all the pins will keep their shape data. But the wires that were connected to the visual graphic shape is now disconnected.
