FortiNAC - Administrator accounts with privileges to create Guest Wifi accounts

I realize the following is a not so great idea but would like to know if this is even possible since management may require it.

Is it possible to give all users with a valid AD account permissions to create pre-provisioned guest wireless accounts in FortiNAC? 

Based on the following snippet from the FNAC admin guide, I can't use the AD Domain Users group: 
"The domain users group cannot be used to set administrator privileges because user details for users in that group are not populated in FortiNAC when a directory synchronization is done."

So, before I ask our AD admin to create a new group named something other than Domain Users and add all user accounts to it, I'm posting to see if this is even possible.
