How to clone a Dashboard Template
Navigate to the Template section by clicking Templates in the left side menu of your Home page.
Once there, click on the Sections tab. This was recently updated from Dashboards in preparation of a new feature coming later in 2023.
Once there, click Create Template in the upper right of the page.
Next, select the source that your template will start from. To clone a dashboard template, select "Start from a template".
Next, select the dashboard template you'd like to clone. You can clone either a pre-configured template, or a custom template that you've already saved. Once you've made a selection, click "Continue".
From here, you can customize and modify the new template as you see fit via the normal dashboard template customization process.
