Order stacking is an option to group some orders in one route for a specific courier.
You can open groups of orders and change the delivery route, add new orders or remove them.
When you want several orders to be delivered by the same courier, you need to group orders in one route.
1st option:
Click on the “multi-select mode” 
on the dashboard screen, then choose the orders you want to group in one route and click on the “associate” button (screenshot 1).

You can open the route menu by clicking on the orders group card. Here, you can change the delivery route order by clicking on the order arrows, associate the route to another courier, refresh the route or disband it (screenshot 4).

*The route is built automatically by the system along the fastest route and orders grouping criteria. To learn more about order grouping criteria, refer to Orders grouping criteria | Algorithm settings
Also, you can find information related to the route like delivery time, distance, etc.
Every order group/route has its own unique identification number. You can find the order group/route identification number in the group card or in the courier route card (screenshot 5 and 6).
