Hi Governing Duck, could you elaborate, please? The Notification options for a pipeline are stored in YAML in the same pipeline, so you should be able to add them once the pipeline has been generated in Lightspeed. Alternately, you could speak to the lightspeed admins to allow addition of notifications in the generation phase.

You could also look at Centralized notifications to decouple pipelines from notifications: https://developer.harness.io/docs/platform/notifications/centralised-notification/
