Disable collisions between NavMeshAgents

I have several monsters wandering automatically with Nav Mesh agents…
Sometimes they cross each others paths and get stuck a little…
Also my player is using a navmeshagent to move around.

I can’t find an option to turn off this collision behavior. I just want them to walk trough each other. How could I fix this?

Thx

In unity 5.2, you could set the Quality of Obstacle Avoidance in NavMeshAgent to None.
