Firewall filter source address query

I have the following firewall filter in place:

firewall {
    filter VPN {
        term VPN-Source {
            from {
                source-address {
                    xxx.xxx.xxx.xxx/32;
                }
                destination-port 500;
            }
            then accept;
        }
        term IKE-BLOCK {
            from {
                destination-port 500;
            }
            then {
                reject;
            }
        }
        term else {
            then accept;
        }
    }
}

I'd like to add an additional souce address for 'either or' or 'both' sceanrios, is it simply a case of adding a new line under source-address or is more complicated than that?
