Plesk with Alias Domains


Dear Let’s Encrypt Community,

first of all, thank you so much for all your efforts.

The server is running Plesk Onyx Version 17.0.17.
The website has two domains.
One is a real domain in Plesk, the other is an Alias, but without a redirect.
The website needs to be accessible from both domains.
I know that Plesk has a Let’s Encrypt Plugin.
Unfortunetly it does not include the Alias Domains.

I managed to create a working certificate via

./certbot-auto certonly --webroot -w /var/www/vhosts/ -d -d

It creates a few files, which i can manually copy&paste into the Plesk Gui and everything is working great.

Does anyone know a way to automate this process?
Or maybe if the Plesk Plugin will ever include Alias Domains?
