      Subnet 1 - Routes out to the Internet though Internet Gateway
      Subnet 2 - Rotues to the internet through NAT on subnet1
      Subnet 3 - Rotues to the internet through NAT on subnet1
      Subnet 4 - Rotues to the internet through NAT on subnet1
      Subnet 5 - Rotues to the internet through NAT on subnet1
      Subnet 6 - Rotues to the internet through NAT on subnet1
      Subnet 7 - Rotues to the internet through NAT on subnet1

      What I am trying to do is route a single server on Subnet 1 through the NAT as well. The route table is controlled at Subnet level. So If I change the subnet routeing rules to go through NAT it breaks.

        I know nothing about AWS routing - can you setup two IPs on the Subnet 1 "router" interface. I know it's not a real router - it's all in software, but I don't know what else to call it.

          Devices are not configurable. Both NAT and IGW have zero configurable options. You just create them in AWS

            You need to setup the EC2 instance with a WAN Dynamic IP (Elastic IP address). Then just go through the Internet gateway and have the security group blocking incoming traffic over the Dynamic IP provided to the EC2 instance.
