Audio Playlist

Version: 2008
Operating System: Mac OS X 10.5 (Leopard)
Processor: intel

I recently bought a Mac and installed Office 2008. I was using a laptop
with Windows XP and Powerpoint 2007 to create presentations with
background music. On the Windows machine, I inserted a m3u playlist into
the first slide and then set which slide I wanted the background music to
end. I've tried to do that in Powerpoint for Mac but can't find any way to
insert a playlist. Is there any way to do this on the Mac?
