There is no standard way to do this, but, from your question I see that you want to append a sibling node after the current selected node. As you already have a reference to the selected node, you can achieve this like so:

var selectedNode = Ext.getCmp('treepanel-id').getSelectionModel().getSelection()[0],
    parentOfSelectedNode = selectedNode.parentNode,
    selectedNodeIndex = parentOfSelectedNode.indexOf(selectedNode);

parentOfSelectedNode.insertChild(selectedNodeIndex + 1, {
    text: 'New sibling node',
    leaf: true
});
