Per this article, the Assembly Group post-numbering method states that it will re-number single parts like this: 'pa-B100' with 'pa' being the single part mark followed by the main part mark or assembly number as '-B100.' Looking for the ability to have the main part mark first.
Example: B100-pa
Another example would be if the assembly is 'A', let the single part mark be 'a' for a final designation of Aa.
If including the drawing number in the BOM, let it be 01-Aa (drawing number, 01, followed by main part, A, followed by single part, a). Dashes optional.
