You can easily add new cells from your source file to your app at any time. This way you do not need to create a completely new app if small changes to the source file have been made and you decide to provide additional information in your app.

To add cells to your app, proceed as follows:

1. Open the app in the web portal.
2. Go to (1) "Edit" and select "Add cell" or (2) got to "Add Element" and select "Cell".In case your app consist of multiple pages, check if the desired page is visible in the preview, as cells selected in the next steps will be added to exactly this page.
3. Select the desired cell from the Excel spreadsheet preview on the right.
4. Adjust the created element or (1) add another cell as an element.
