How does Cisco SD-WAN prevent loops?

In Cisco SD-WAN, all OSPF routes are distributed into OMP. What happens when I have 2 routers at the same site, and I distribute OMP into OSPF?

I'm worried that routes brought into Router A via OMP->OSPF redistribution will be advertised out Router B, since they are OSPF routes.

I'm used to tagging routes and setting up route maps to prevent this. Does Cisco SD-WAN have some sort of built-in method to handle this?
