Using pfsense DHCP server for multiple lans on one lan port

[lanman]

My network looks like this.

internet 195.84.205.0/24
                        |
                  |–--------|
                  | pfsense |
                  |----------|
                        |
                        | LAN 10.46.1.0/24
                        |
                  |---------|
10.46.2.0/24--| router  |--10.46.3.0/24
                  |---------|
                        |
                  10.46.4.0/24

As you can see my LAN is 4 different networks.
What I want to acomplish is using pfsense DHCP server for all 4 lokal networks.
I can do this using dhcpd.conf but I rather do it using the webgui if that is possible.
Any ideas someone?
