Question Multiple admin domains with SSL

[addvilz]

I have a Plesk deployment and the admin panel is configured to be 2 different domains:

• something.internal.lan
• something.external.com

Admin panel is secured using LetsEncrypt for something.external.com. I would like to retain both URLs because one of them (.lan) is routed using private overlay network, and I have OS level + panel's own restrictions in place to only allow admin login from internal LAN.

Is there an option to configure Plesk admin panel to use whichever SSL is matching the DN? Say keep .com with LE, and have .lan use custom cert from the cert collection?
