Step 1: Click on the Slide that you want to move or transfer over.

Step 2: Click the drop-down on "Slide" and then click "Move Slide to Chapter".

Step 3: Pick the chapter that you want to move the slide into, and then update any changes you would like to see inside of that. After saving, this should now be in the correct order.

OPTIONAL: You can also use the "Slide Navigator" feature shown on the top right. You will be able to see all of your slides and chapters, and from there, are able to organize them. You can drag and drop specific slides into the location you want which will update the order they are shown.
