How can I monitor traffic on WAN links of my router? I added router with it's LAN IP as a device and NetFlow sensor. Should I add every WAN interface's IP as device with sensor to be able to monitor traffic?

You should be able to use one of the following filters:
Port [any number]
SourcePort [any number]
DestinationPort [any number]
So if you wanted to filter the traffic that is flowing through your wan port and it's port 1 you can put the filter Port[1] into the filter field and it should show that traffic as a separate channel.

Filtering with Interface[ifindex] should solve it. Of course there is no syntax for this option in manual (!)
Interface number (ifindex) we get on router when issue command
show snmp mib ifmib ifindex
