Create subdomain with DocumentRoot based on parent domain DocumentRoot

[EmilianoS]

Hello,

I would like to know how do I create a subdomain with a vhost DocumentRoot based on the parent domain DocumentRoot.

Example:
mydomain.com
DocumentRoot: /var/www/vhosts/mydomain.com/httpdocs

The default DocumentRoot for a subdomain is like this:
subdomain1.mydomain.com
DocumentRoot: /var/www/vhosts/mydomain.com/subdomains/subdomain1/httpdocs

So I would like to have a DocumentRoot like this:
/var/www/vhosts/mydomain.com/httpdocs/subdomain

I want this so I can access the same website with this URLs
http://mydomain.com/subdomain1
http://subdomain1.mydomain.com

The only way I know to do this is by editing the vhosts.conf

There is any other way to do this using Plesk Panel?

Thank you.
