How do you change the root folder of the primary sub-domain?

[studolf]

When you create an account, the root folder of your primary sub-domain is the public_html folder. Let's say I want to change it, is this possible?

 

For example, I'd like to change the root folder of my primary sub-domain from public_html to public_html/primary. I'm going to install joomla, so I'd prefer not to have files scattered all over the public_html folder. I'd rather keep them in a separate folder, hence they're easy to manage.

 

How do you do it?
