Show the total in Data Labels

Hi, is it possible to show the total of both columns in this bar chart.

Is it possible to show the combined values of the pre-percentage and the percentagepositive as the data labels? (ie. bar1=102.24%, bar2=101%.. etc), without having to edit the nature and the look of the graph. As I want to show the user the values with greater than 100% in a different color.
