Corridor Modeling XS labelling - Negative cross-slope label?

Is there a way to get the corridor modeling XS labeler to label negative cross-slopes (i.e. normal crown) as "-2.00%"?  In near-flat cross-slope situations it is very difficult to tell which way the pavement is sloping (other than comparing elevation labels).  The old criteria method of labeling cross-slopes would differentiate between a negative and positive cross-slope.
