Additional fields add-on doesn't add fields to manual appointment creation.

I've found the add-on 'Additional fields' extremely useful for gathering more important information about users signing up for an appointment.

However, I noticed that this seems to only work for the front end and doesn't create fields in the section where I add appointments manually.

What would you recommend?

1. Developer to code in the additional fields so they would show in the front and admin area? - Is this even possible?

2. Forget about adding a new appointment in the admin area and just do it for the client from the front end? This is actually the only way currently to do it if you are going to want to add manually and charge the client while on the phone see here

Or is there another method?
Thanks
