Flow offers a convenient interface where you can manage custom fields and data.
You can add Dynamic Fields to virtually any Data type (Story, Topic, League, Team, Game, Media)
Make Your Own Custom Fields
In which ever data type you have, search for either the Tag or buttons.
Open the Make Your Own row
Enter a field name. (This will translate to ^datatype.%FIELDNAME% in XPression) Example: ^custom.JerseyNum or ^scores.vteam.JerseyNum or ^story.jerseyNum
Enter the field data manually.
Specify whether it's a text, number, date-time or toggle field etc. See Dynamic Field Types for more.
Save your changes.
In XPression:
Existing Custom Group and the No Group Folders
Expand any existing custom group folder or the No Group folder to specify data for pre-defined fields.
Field data may already be pre-populated via an integrated data feed. You can edit pre-populated data any time.
Quickly tab from field to field using the TAB key.
Save your changes.
