Option to add an image as the frame background.

The only thing I wish Miro had is the option to add an image as the frame background. There is an option to change the color and also the option to change the frame style, but there is no option to add an image as a background, which makes it very difficult to add an image as a watermark. I have to do it manually, upload the image, adjust it to the size of the frame, place it on the right layer and then leave it in the background, without hiding the texts or shapes for example. It is a lot of work, because I have a lot of texts, objects and images in each frame, so when I select everything and click to change to a specific layer, they do not change, so I have to change by group, and then upload the image and add it to the background, which is very frustrating and tiring. Please add the option to add an image directly as the frame background, it is already possible to change the background color and style, but it is not possible to add an image as a background. I have to do this manually and it is very laborious.
