Request help creating slideshow with Organizer

Am using Elements 2023 Organizer to create a video slideshow.  Most of the themes display two or more pictures on each "slide" somewhere within the completed video.  Is there a way to constrict this to only display a single picture for each slide?

The workaround is to create several videos, adding or deleting slides until I have footage of every picture on its own slide, then cut and splice them together within Premiere Elements to render a full video as desired.  But that's dumb and time consuming.  There must be an easier way.
