Yes it's available
but I need to separate it in services starting and stopping it when neeaded
- But I can't find anyway to start an ssl request for them all at once
- also I can't also set the site domain and the subdirectory at the same time
- tenants are not accepted in subdirectory binding also

No action for multi-site cert, Also no side panel to manage them,
and no file in the add cert so I can't use ca-certificates and point to the result cert file ( by the way ca-certificates always update )

Tried to see Therd party plugins to get a ca-cert manager but found nothing
This may be better in terms of setting it up the easy way
