You could try to construct proxy_ssl_name based on upstream address, e.g.:

    map $upstream_addr $name {
        ~\Q192.0.2.1:8000\E$ first;
        ~\Q192.0.2.2:8000\E$ second;
    }

    proxy_ssl_name $name;

Note well that $upstream_addr may contain multiple addresses, use it
with a special care.  See for details: http://nginx.org/r/$upstream_addr
