Guest SSID - email permission?

We have some FortiAP's set up with our FortiGate, and a few SSID's assigned around.  The last SSID to be created is for guests.

One of the things that I enjoy about Cisco Meraki access points is the ability to require guests to get permission from an employee via email.  After joining the guest SSID, they would be thrown to a captive portal that would require them to enter their name & the email address of an employee.  The email address would be required to match the company's domain(s) (etc *@mycompany.com).  The employee would receive an email with links to approve or deny guest access.  This allowed a measure of security and responsibility, without being a burden on IT to authorize each guest.

So... is there anything like this available with FortiAP ?  

(We are not looking to collect guest email addresses, or create accounts for guests in our Fortinet environment.)

Thanks!
