Reselling Servers?

Hi,

Is it possible to resell servers from another company with WHMCS, so that clients get a control panel to manage their servers, like in the screenshot? And get an email with the new server details through my WHMCS?

I know this is in WHMCS, but is this possible because of an addon, or is it standard in WHMCS? If this is done with an addon, which one?
