tfh Another option would be to make like a general location when you can do settings that are usefull server-wide or accross multiple hosts and give the option to "copy" the settings you have just made to selectable hosts.
This feature has always been there in X2 since day 1 😲 That's option Copy Configuration From in Hosts > Add: https://aprelium.com/data/doc/2/abyssws-win-doc-html/hosts-add.html .
You can create a host, fill its parameters and possibly keep it stopped. The host can then be used as a template.
Later, when adding a new host, you will be offered to initialize its configuration from an already configured one or use a clean room setup. So at that step, you could copy from the template host.
But as you can guess, this is only useful when defining the host: Parameters will be copied and not inherited.
