If you wish to create routes with constraints like Max Duration, or Max Stops, you can set these Multi Routing constraints under Goals tab.
When you set these constraints, make sure they do not contradict each other. Meaning, you should not set a single route with 10 stops if you have 15 stops. Otherwise, you’ll end up having one route with 10 stops and the rest of the addresses will be left unallocated, as shown below:
