Yes. To do this, set up a whole new organization in Zammo with the second invocation name and submit it to Alexa. Zammo can mirror the content of the two organizations so that whether someone asked a question of [invocation name 1] or [invocation name 2], the user would have the exact same experience. You would only have to manage content in the original organization.
You would need to purchase a second Zammo license to go this route. Please reach out to your Zammo sales rep for more information.
