Add a Caption To an Existing Slide

## Can you think of a better caption?
Each slide can have more than one caption. Check out the current slide show and add a caption (or two).
If you need help, check out the Appendix in the training manual.

Open the current slide show and review its existing captions; the issue does not identify a particular slide. Use the Appendix in the training manual for guidance, then add one or two captions to an existing slide and confirm the slide show displays them.
