Styling tree grid error row

Hello,

I'm using SmartClient_v91p_2014-05-04_PowerEdition.

I have a tree grid with one field and hierarchy.
I'm using to set an error indication on this row (see picture). I couldn't find any way to change the error icon, the error icon position (I want it to the left of the text) and set new style to the row in case of an error. (see picture 2 for wanted result).
