To add a new slide to a VividCharts Narrative, start by navigating to the Narrative record that you want to add the page. Once you are here, click the Add New Slide button in the Slides list.
Once the Add New Slide button is clicked, the Create New Slide modal will appear. In this modal you're able to adjust the Slide's title and select the Dashboard that this Slide will use.
From the Narrative Settings column you can adjust the Title as well as the Sharing settings of the Narrative.
An additional piece of functionality that has been added in 3.20.1 is the ability to reorder Slides directly from the Edit Narrative page.
To do this, you'll click and drag the reorder icon to the left of the Slide title in the Slides list.
