CL_GUI_ALV_TREE has no dynamic breakdown

Hi experts

In example program BCALV_TREE_SIMPLE_DEMO , there is 'Change Breakdown' toolbar button option which I believe is available because we add the sorter changing  table CT_SORT while calling method SET_TABLE_FOR_FIRST_DISPLAY of CL_GUI_ALV_TREE_SIMPLE.

Using this CHANGE_BREAKDOWN option, users can choose the hierarchy fields on the fly and sort as per need

Q1. Is it possible to achieve this using the CL_GUI_ALV_TREE class?

Q2. If I decide to use CL_GUI_ALV_TREE_SIMPLE instead of CL_GUI_ALV_TREE what major features will I miss out?

p.s : Some features I cannot do without are :

I want to construct a tree with all nodes having check box , highlight-able rows , perform aggregations on qty fields , retain the drill down of tree while I do a refresh with new data in the tree.
