Render Result as Texture Image

I found I cannot use Render Result as Texture Image
I guess there were some conflicts caused by this action?
How about allowing users to duplicate the render result to a texture image which will be used in shading

I’d love to see this as well. One use case I’d hoped to try was to render out a heightmap from an orthographic top-down camera and use the output in a displacement modifier elsewhere; it’d be great to not have to save the texture file manually each time.
