Adding fields to Bookings

Hi:

  1. Is it possible to add a custom field to the Booking database? There does not seem to be a way to do this.

  2. Also, although I have entered categories for my Bookings, they do not appear in the database so it is not clear how to use the category to create custom category pages.

  3. So, it looks like Wix has buttoned up the Bookings database from editing and customization. Is that the case?
