Zoho Form Premium suscription - how to merge user info from Zoho Directory to Zoho Forms Reports

Hi. We want to merge the info in the forms submited by our private users, with some of the fields completes in Soho Directory (for example with name, surname, and other personalized fields we create in zoho directory).
In report entries we can't add aditional fields of user information in zoho directory, and neither can we add this fields in email notifications. How we could do this ? Thks
