FTP only to SubDomain Folder

[Rookie]

Hi,
I want to create an extra FTP account for another user. But I only want that user to be able to use a sub directory ONLY.

Example: subdomain.sitename.com
(I only want them to have FTP access to "subdomain" NOT "sitename.com")

Can this be done? If so, how would i set it up in the FTP accounts section? (Example: what do I put in the "Custom Field" when creating the extra "FTP Account"?

Thanks
Rookie

Opps! Sorry...

It's ok, ignore my post, I worked it out

Just in case anyone else has to do it and has limited knowledge like me here it is:

/home/<user>/domains/<sitename.com>/public_html/<subdomain>
