This answer may be a bit late, but: The "Time Card Portal Container" widget instance [sp_widget] contains a comma-delimited list of tables in the "Additional options, JSON format" [widget_parameters] field. These values are passed through to the "Time Card Grid" widget and used to populate the list of tables in the Angular ng-template "add-task-modal." By modifying the options in the widget instance, you can change the list of tables presented without modifying the widget code.
