How to reorder categories in TCategoryPanelGroup (Delphi XE)

I have a TCategoryPan开发者_开发技巧elGroup instance dropped on a form. I would like to allow the user to reorder the categories. In tryed to reorder Panels[] property - which is a TList - but this doesn't seems to work.

Any idea ?

Effect this change by modifying the position of the panels:

CategoryPanel2.Top := 0;
CategoryPanel1.Top := CategoryPanel2.Height;
