I understand the Pause Time and can add this, but the Angular Speed and Acceleration are already taken and used from the NavMeshAgent component. Do you want to set Angular Speed and Acceleration different for each Patrol action?
Only If possible. Because it would declutter from having to do a massive tree and branches. Imaging the tweaking you can do for an NPC patrolling. in one go, each waypoint different speed reaction time and the best of all, each waypoint could send an event. Every time it reach a waypoint it announced. I could dream about it already.
