setting the rowSelector text on the footer row

How Would I set the row selector text for the footer row?

The content of the footer row selector is linked to the bottom model, so obj.setBottomText("abc") should set the text

obj.setFooterVisible(true);
    obj.setSelectorVisible(true);
    obj.setSelectorWidth(40);
    obj.setBottomText("abc");

Thanks, Alex! That's exactly what I needed.
