Wan link state notification

Hi, I just joined a new company and we have two different office buildings. One building has Sophos XG230 Firewall and the guy who used to work before me configured the firewall notification setting in such a way that when any WAN link is down, we get an email with the subject "Gateway BSNL_WAN_1 100 Mbps Went Down" like this. We just purchased two XG550 FW recently and I want to configure the same notification setting. But the problem is when I get a notification it just tells the state of WAN port in the email body. How do I configure so that I get an email with subject of WAN port down, as I get in my old firewall?
