Bookings information not populating on bookee's confirmation email

Our form for scheduling employee onboarding has questions asking the manager/booker for the joining person's name. When a manager/booker submits a booking request to us/bookee, the booker receives confirmation of this information they put in under "Your Details", but we/bookee (the one who needs this information) do not see this information at all (neither subject or email body content). There seems to be no way to customize the confirmation email that we/bookee get, and the "additional information' section is what we fill out beforehand. 

How can we get this information the booker provided? (Is this case, 1 person named "Test person")

Is there a way to update/customize the subject line or body of the confirmation email to include this, rather than just "New booking: for HR Onboarding Meeting (booking name we set)"?
