Need HELP setting time-length for captions

Can someone help me figure out how to adjust the length of each caption on a slide show. For this particular slide show, the first photo has a 30 second length and I want to overlay a succession of short captions but I only want each caption to last a couple of seconds. I only see time setting options for setting the length of the slide, but none for the caption itself. Thanks in advance!

This has been answered for you in your other thread on the same subject.

It is always better to ask the question only once under one heading, it saves searching backwards and forwards.
