[Prism5] - A question about survival curves in GraphPad's Prism5

Hi all.....I'm trying to get some survival analysis done in Prism 5. I've been able to generate the graphs no problem, but what I cannot figure out is how to add in the patients at risk for each time point along the x-axis. In SAS, it's fairly straightforward but unfortunately the team I'm working with thinks the graphs look better in Prism. Any ideas? I have tried everything, read everything I could find, but no luck.

Any help would be greatly appreciated......
