Webmail and let's encrypt certificate...

[Remitur]

I configured the server in order to make webmail available to the URL webmail.example.com instead of example.com/webmail ... but doing so there's an issue with LE certificate.
DA manages and creates the LE certificates for:

• root (example.com)
• ftp.example.com
• mail.example.com
• pop.example.com
• smtp.example.com
• www.example.com

But not for webmail.example.com ... :-(

How can I do to configure DA in order to generate the LE certificate for webmail.example.com ?

Anyone here to help me, please?!?!

O can also ask the same question in a widest and more general way:

How is it possible to enable a let's Encrypt certificate for a subdomain different from the default?
That's to say: how can I enable a let's encrypt certificate for, i.e., blog.example.com ?
