A sorting name is used exclusively for a Speakers page type. This text field allows speakers in the list to be sorted in alphabetical order by whatever is in this field. For example, you could use speakers last name to order the list in alpha order by last name. E.g. if the speaker’s name is 'Dr Gordon Wardell Ph.D' - use 'Wardell' for sorting.
A sorting name does not display in the app and is only used as a sorting tool.
