Create Zones and allocate imported orders to zones
You can create new zones within "Zone" menu. Then you can import orders from Excel file which will be automatically grouped into your zones.
After importing excel file, you will see that orders are imported by zones. Manifest names will be created as the name of the zones. Orders that are not in zone range will be unallocated/unassigned.

You can go into the manifest that got created by zone and click "Optimise route".
Assign driver/vehicle
Click into the manifest and click "Edit" to assign driver and vehicle.
Your route optimisation is ready!
