Hi DH23 ,
I don't know what you mean by Bulk Generate. ATUM Locations is a hierarchical taxonomy. You can create terms and subterms with as many levels as you need. However, they can't be bulk-created (though you can use a taxonomy importer plugin).
What I can't know is if this meets your needs, sorry. I'd need more specific info about what you want.
Best Regards,
José Andrés
