[Feature Request] Allow appointments created via RTB on Widgets to be created for the user

Right now we can attach RTB to Widgets, but the process means that the appointment isn't booked with the actual user 'calling' the widget. In GHL specifically, the appointment is simply created-for and attached to the first contact it can find. We need a way to allow customers to set it up so the widget creates an appointment and attaches it to the email address provided during the call.
