Substitui o arquivo virtualhost por include

Question

Atualmente tenho o host virtual gerado automaticamente a partir do cpanel da seguinte forma:

<VirtualHost 162.144.xxx.xxx:443>
  ServerName mydomain.com
  ServerAlias mail.mydomain.com www.mydomain.com
  DocumentRoot /home/mydomain/public_html
  ServerAdmin [email protected]
  UseCanonicalName Off
  CustomLog /etc/apache2/logs/domlogs/mydomain.com combined
  <IfModule log_config_module>
    <IfModule logio_module>
      CustomLog /etc/apache2/logs/domlogs/mydomain.com-bytes_log "%{%s}t %I .\n%{%s}t %O ."
    </IfModule>
  </IfModule>
  ## User sajadeal # Needed for Cpanel::ApacheConf
  <IfModule userdir_module>
    <IfModule !mpm_itk.c>
      <IfModule !ruid2_module>
        <IfModule !mod_passenger.c>
          UserDir enabled sajadeal
        </IfModule>
      </IfModule>
    </IfModule>
  </IfModule>
  # To customize this VirtualHost use an include file at the following location
  # Include "/etc/apache2/conf.d/userdata/ssl/2_4/mydomain/mydomain.com/*.conf"
</VirtualHost>

Eu preciso remover o Documentroot dessa configuração. Eu quero fazer algo assim, não editando este arquivo, mas substituindo este arquivo:

<VirtualHost *:443>
        ServerName example.com
        ErrorLog              /var/log/apache2/external-https_error.log
        CustomLog             /var/log/apache2/external-https_access.log combined

        SSLCertificateFile    /etc/ssl/example.com.crt
        SSLCertificateKeyFile /etc/ssl/example.com.key

        ProxyPreserveHost       On
        ProxyPass               / http://127.0.0.1:8080/
        ProxyPassReverse        / http://127.0.0.1:8080/
</VirtualHost>
