You can group columns on master (master of masters, etc.). For this AGE is the Grouping property.

public class Grouping
{
    /// <summary> 
    /// Hide empty groups (without objects) 
    /// </summary> 
    public bool HideEmptyGroups { get; set; }

    /// <summary> 
    /// Sort group 
    /// </summary> 
    public ColumnsSortDef MasterColSortDef

    /// <summary> 
    /// The name of the master (not the property of the master) 
    /// </summary> 
    public string MasterName 

    /// <summary> 
    /// Property name in the wizard that will appear in the group header 
    /// </summary> 
    public string MasterCaptionProp

    /// <summary> 
    /// Limit on group 
    /// </summary> 
    public Function MasterLimitFunction

    /// <summary> 
    /// Representation which will be read group 
    /// </summary> 
    public View MasterView
}

Example (gang wizard “Tiplady” as the group header will be used Tiplady.Name):

ctrlЛапа.Group =
                new Grouping(
                    new ColumnsSortDef(Information.ExtractPropertyPath<Лапа>(x => x.ТипЛапы.Название), SortOrder.Desc));
