NPS network policy with multiple Client ip4 addesses

I have a wireless policy on my NPS server with the primary wireless controller added using a Client IPv4 address entry in the policy. I want to add the backup controller as well but it seems it is adding it as a and condition. I need it to be added as an or condition when the primary controller is unreachable.

How can I add multiple Client ip4 addessess in a Network policy with an or condition? An and condition would require both to be reachable. 

thanks.
