It is not possible in shared hosting account, but only in Reseller hosting account.

You can manage all domains together under one cPanel shared hosting account. It means you have just one control panel where you can manage subdomains, Addon and Parked domains, databases, Email and FTP accounts etc. for each domain.

If you need to have separated account for each domain you want to host with us, you should think about Reseller account. In Reseller account you can create as much separate hoasting accounts for your domains as you need.
