In 7.2.1 designer studio when the application stack includes "PegaMarketingNBAA_FW" application, we can change Next Best Action Settings where options to "Manage Intents", "Manage Negotiation Groups " , " Manage NBA Actions" appear. Attached is a screenshot.
For 7.4 We are trying to find out how to get that option in the drop down. Its currently missing from the designer studio . Attached is a screenshot.
