In your SSL Template (https://www.zabbix.com/de/integrations/ssl), we need to define the Macro {$CERT.WEBSITE.HOSTNAME}, at the moment we need must configure it on every server seperately, that can be really annoying if you've a lot of them. We use for each server an all-in-one-cert, where the aliase the websites which the server has.

So it would be really nice if we can use {HOST.DNS} as value (look at the screenshot), it would be much easier to use...
