AP assigned NAT mode

[Allerton61]

We have seven Meraki networks and we have one identically named SSID in each for staff that move between those networks to make getting Wi-Fi easy. We configure Meraki AP assigned (NAT mode) addressing for each network, and it works great. However i'd like to be able to have a different custom DNS server for each network, but if I apply an IP address to one SSID it appears in each of the network instances. Is there a way to isolate the DNS entry to the particular network SSID?

Thanks

The DNS used in NAT mode is whatever the DNS is configured on the AP itself.

So how does this SSID setting differ?

Are you using a template for multiple networks?  This setting could be part of the template.
