Thanks Philip. I have not had a chance to try it yet but in looking at how I would do it, I expected to need to be able to configure it on an interface somehow. I even stopped by the Meraki zone at CLUS the other week and asked. I was told to assign it to an interface, even if that interface was not in use but I cannot use those IPs in NAT if I did it on a non-WAN interface. I will certainly give this a shot when the addresses get assigned this week.
