This is not a bug, we just design as this. If need, maybe this is a feature

@Ideaman4u, I think you misunderstand what the MOUNTED attribute is for. The MOUNTED attribute is a **Bill of Materials (BoM)** attribute. * It is not a **PCB** attribute. It is used to indicate if a component is to be mounted on the PCB *when it is assembled*. To illustrate by example, suppose you have a PCB with a microcontroller that is user programmed for the prototype PCBs but in production, the micro is supplied pre-programmed by the manufacturer. The prototype PCBs will need a programming header connector and may need another connector for debugging purposes but the production PCBs do not need them fitted. * The point here is that the prototype and the production boards *are built using exactly the same PCB*. They both have the same PCB footrpints and tracks on them. They just have different parts fitted according to the Bill of Materials (BoM). So for the prototype PCBs, the BoM is run with the MOUNTED attribute for all the parts including the programming and debug headers set to `Yes` but for the production PCB, the BoM is re-run with the MOUNTED attribute for these two headers changed to `No`. If you try to make the MOUNTED attribute a **PCB** attribute then you in effect are implying that the PCB with the MOUNTED attribute set to `Yes` will be made with PCB footprints and tracking for all the mounted parts whilst a PCB made with the MOUNTED attribute for some of parts set to `No` will be made with those PCB footprints and associated tracking, not present. * Therefore by changing the MOUNTED attribute you would be designing two *different* PCBs. That does not make sense because these are in fact, two different PCB projects not one with two stages in its lifecycle simply indicated by the status of the MOUNTED attribute in the BoM.

@andyfierman You were correct. I did not fully understand the term Mounted. Thanks for the clarification. Sam
