Better AI Journeys tile management and bulk deletion

Business problem

The current AI Journeys interface lacks efficient management tools for editing complex workflows, making it time-consuming to delete multiple tiles or restructure steps without manually tracking tile code numbers.

Wished result

A more intuitive AI Journeys tile management system that includes bulk deletion capabilities, a 'jump to step' selector that uses step names instead of codes, and the ability to remove 'AI routing' tiles regardless of downstream connections.
