Yes, nanoCAD has a feature to automatically generate the Bill of Materials (BOM), but this option appears to be available only for nanoCAD Firealarm. I have searched its official website, and the only place there this term appears is for the nanoCAD Firealarm.
You can check for more info using the following URL: http://nanocad.com/page/nanoApps
Additionally, I would recommend contacting the developers. They should provide additional info about their programs: http://nanocad.com/page/Contacts
