В 2009 можно с помощью AOTDuplicate

static void Job196(Args _args)
{
    TreeNode    treeNode, treeNodeDet;
    XInfo       xInfo = new XInfo();
    ;
    treeNode =  xInfo.rootNode();

    treeNode = treeNode.AOTfindChild('Data Dictionary');
    treeNode = treeNode.AOTfindChild('Tables');
    treeNodeDet = treeNode.AOTfindChild('CustGroup');

    treeNodeDet = treeNodeDet.AOTDuplicate();
    treeNodeDet.AOTsetProperty('Name', 'DLCustGroup_NV');
    treeNodeDet.AOTsave();
}
