You can assign an identifier to an individual component instance in an assembly. To do this, you need to edit Component properties complementing Component reference.

E.g, you can use Component References to store reference designators for a printed circuit board assembly or an electrical wiring assembly. When different instances of the same component have different values Component references, these instances can be displayed as separate line items in the BOM.

After you define the references, the name w appears in the assembly tree brace { } at the end of the component name string.

In the drawing, you can add the appropriate column to the BOM.

At the same time, you can insert a link that displays the Component References. The condition is, however, such, that an identical column must be included in the BOM. Also remember about reconstruction, preferably forced CTRL + Q so that the information appears on the defined link.
