What I am looking for is to have 2 different networks (SSIDs) with 2 different Gateways

My Decos X60s are in Router mode where the main router connects with a cable to network 192.168.10.0 and on the WIFI part, it creates it's own network on 192.168.68.0

The gateway to the outside is my Broadband Router 192.168.10.254

Now I have another router on that network that has another Internet connection (192.168.10.10)

What I want to do is to be able to create another Deco Network (Lets say - 192.168.69.0) and route this network via the other internet connection through router 192.168.10.10

So I would have

Clients A --> DECO_SSID_1 --> Deco Network 192.168.68.0 --> DECO DEVICES --> 192.168.10.0 network --> 192.168.10.254 gateway

Clients B --> DECO_SSID_2 --> Deco Network 192.168.69.0 --> DECO DEVICES --> 192.168.10.0 network --> 192.168.10.10 gateway

Is this possible ?

Thanks
