sw-part number not bi-directional.....

Partnumbers in SW have been a real pain. I've always wanted to use the 'use specified name' or if I can set the name as the configuration - as this can then show in the tree.

Unfortunately I can find no way of accessing that parameter within a note, so I had to introduce another custom property and hence now have the number duplicated. I've since started using the sw-part number which is already there in SW.

However I changed this value in my BOM but it did not reflect in the part, all the other obvious properties do change.

Why would the 'sw-part number' be singled out?
