I created a Quad NAND gate in the library editor with the following properties:
- All units interchangeable.
- Edit pins per part or body style. I want Vcc and DGND only on Unit A.
The part was created and tested successfully.

When this part was added to the schematic, i wanted to change the "Value" field to a different value.
(Right-Click on component -> Edit Component -> Value). I did the change initially on unit A.

I expected that changing the "Value" field on one unit would apply to all units of the device as the "Value" field represents the device as a whole (i can't think of a case where it wouldn't).

However, the change only applied to the unit where the change was performed. This means that changing the "Value" field has to be performed for every unit individually, which manageable until a device has many units spread over a large schematic.

BR,

I can replicate being able to change the value of just one unit of a multipart eg 7400 Unit A to 74LS00 and the schematic displays the values as different in the same part.
But, when I run Annotate I get a pop up box "kicad Warning Different values for U1D (7400) and U1A (74LS00)" and if I run ERC, I get "Different values for U1D (7400) and U1A (74LS00)
Annotation required!"
