Many, but not all, of the transitions in PowerPoint can be customized.

Select the slide that has the transition you want to modify.

On the Transitions tab, in the Transition to This Slide group, click Effect Options and select the option that you want.

In this example, a Gallery transition is applied to the slide and the From Right option is selected.
