Does anyone know how I can utilize the address book in Outlook to populate text on a PowerPoint slide?

I created a call list macro that puts people's contact info in a table on a PowerPoint slide. This is not as flexible as I want it to be because:
1) It only covers specific people (hard coded for my region)
2) The data never changes, so this creates a big maintenance issue

If I could get the data from the address book, I think this would solve both my problems as it would be live data (and I would never have to worry about updating the information if, for instance, someone's title changes or they leave the company).
