In setting up a new custom data group under the 'used for' selection, the first option is Contacts -> Any. The default selection under Any is Students. Please see attached screenshot.
Problem is I can't find where this has been option has been set in CiviCRM and how I can utilize this option. I've created a custom data group using Contacts->Students, and while the fields are available for me in profiles and I can enter this data from a profile, where this data is rendered I just can't find.
