If you want to divide in different rounds an order, you need to activate the following modules: 

Back office> configuration>your module>Order sending ticket> Print staggered orders in the kitchen

Once that is done, go to the app, refresh it and open a new order. 

First of all, you choose the first dish: this is your "Direct" Then you click on “Add sending” and you choose the second dish: this is the "Sending 1"

You can repeat this action as many times as necessary.
