Hero bloc image choices

When choosing a background image for a Hero bloc it would make a lot more sense if we could automatically choose separate images for mobile, tablet and desktop within a single bloc.

I’m currently working on a site, where I wish to to add an image of a model lying on a beach as the hero image, but when it goes to a smaller device size, or even a smaller desktop size, large chunks of the image are lost and it doesn’t seem to be very responsive at all.

With an image like this it looks like I’ll have to add the bloc three times, while clicking on visibility options and it’s all too fiddly. I just want to add the appropriate sized images in one place and let Blocs decide which one to serve based on the user’s device type.
