@MBR Or… you could simply create an empty frame containing only the logo/other graphics in top and/or bottom and then copy-paste it when creating new frames. You could even save it as an internal template. 

Hi there, following up on this older Wish List request with an update. After further review, we've determined that the functionality requested here is already available on the platform by using Templates. You can find and use an existing Template, or create your own custom Template, and reuse it for presentations that you need standardized formatting. Learn more about Templates in the Miro Help Center.

With this in mind we will update the status of this request to Existing Feature. Thanks ​@MBR  for taking the time to participate in the Wish List!
