We have added this as a new property GridColumn. We also added ColumnAtField at database adapter to easily get the column for a specific field name, for example
TMSFNCDataGridDatabaseAdapter1.ColumnAtField['Timestamp'].GridColumn.Formatting.&Type := gdftDateTime;
TMSFNCDataGridDatabaseAdapter1.ColumnAtField['Timestamp'].GridColumn.AddSetting(gcsFormatting);
We'll release an update in the upcoming days
