How can I populate the Caption field in SlideShow with the caption text from Organizer

I have entered caption text data on many of my JPEG photo files using Adobe Elements Organizer. I then used the “Save Metadata to files” option so that the caption text is written to the IPTC metadata field “Description”.  I now want to use Create a SlideShow feature in Organizer to create a movie.  I was disappointed to see that the caption text I entered into each photo file is not imported into the caption field for each slide in the SlideShow.  How can I get the caption field in SlideShow to be populated with the text that I have already entered in the caption field in the Organizer?  There must be a way to do this.  If this can not be done then this is a very significant shortcoming of this software.  In the past I have used ProShow Producer to produce picture SlideShows and that software was able to import may of the IPTC metadata fields included the Description Field.
