Hi Marco,

Within SD-WAN overlay network, this is achievable through Application-Aware Routing. In nutshell, in a pure IPv4 network or MPLS based network, QoS will utilise CoS & DSCP to deliver the classification that meets expected quality while in Cisco SD-WAN it has been moved to the application level (noting stops you to use DSCP still). so you can classify or even steer traffic based on application type (DPI engine identify different type of applications). 

Through vManage, this can be configured through the Centralized Policies. Below link should give you a clue on this:
