Waterfall/Stacked Column Chart Labels

I currently have a waterfall/stacked column chart for a series of global
data. The only part I cannot figure out is how to get the labeling correct.
Example, the "red" bar is an increase in spend and the "green" bar is a
decrease in spend, I would like to have labels as such, Red bar labels on top
outiside of the graph bar and green bar labels at the bottom outside of the
graph so you can see the progression across the chart. Is this possible
without manully pulling the labels individually? Thanks...
