If you want to customize your Ribbon in PowerPoint, you’ll want to add some of the commands that were not placed by default within any of the Ribbon tabs. Or maybe you want a particular command available on the Home tab of the Ribbon. Whatever your intent may be, you cannot place any commands within the existing groups that are built within PowerPoint. You first need to add a custom group within any of the tabs available in the Ribbon. Thereafter, you need to populate them with commands.
