BOM Report with Alternates in HDL

Hi,

Is it possible to generate BOM with different alternates automatically in Design Entry HDL?

Example:

STATUS     VALUE     VENDOR     PART_NUMBER          INTERNAL_PN

Pref             47K          Yageo          RC0603JR-0747KL     123-456

Alt1             47K          KOA              RK73B1JTTX4T3J        123-456

Pref is the component used in the schematic design and Alt1 is the alternate part for the preferred one.  I want to list all possible alternates for the the preferred part placed in the schematic design.  Alternates are identified by the Internal_PN.  All parts with same Internal_PN must be displayed in the bom under the preferred part.

Thanks,

Maberu
