How do I setup Site-to-Site VPN connections with multiple subnets at the remote sites?

Greetings.  I'll be configuring site-to-site IPSEC VPN connection tunnels for 1 host site to 2 remote sites. The 1 host site will just have the LAN subnet, but each remote site with have the it's own LAN subnet and the WiFi subnet that will be bridged to the LAN but will have different IP addresses.  In order for the WiFi clients to communicate back to the host is it just as simple as adding their wifi subnet along with the lan subnet as an IP Host and then adding the IP hosts definiions to the initial VPN configuration in the "remote subnet" list, and then adjusting the firewall policy accordingly?  So let's say Main Site is 192.168.0.0 and Remote Site 1 LAN is 10.0.0.0 and Remote Site 1 WiFi is 10.6.1.0.

I, on the host XG unit, create an IP Host for the Local Host LAN then create an IP Host for RS1 LAN and RS1 WiFi subnet.  Then, create the Site-to-Site Profile and add the IP Host for RS1 LAN and RS1 WiFi to the "Remobe Subnet" field?  Is this correct?

And then of course repeating the process for the VPN tunnel to remote site 2...
