Hello xsven,
This is not a part of cPanel, this is a special service that we must provision for you. We have to manually assign a dedicated IP to your site, then we will go buy a certificate for your site and install it.
It is a "hands-off" process handled completely by us because of your qualified hosting plan.
If you are ready for these bonus features please open a ticket with your private account information at our helpdesk (Login to MyGlow account manager and click on "Helpdesk" > submit ticket) and we will add them to your account as soon as possible.
