Highresolution Screenshot

In Blender you can create screenshots ( Window -> Save Screenshot) but they just take the resolution you have on screen, i would suggest a function similar to the Highres Screenshot slider in UE4 which upscales the screenshot to a higher resolution if wanted. Maybe even with AI driven upscaling? This was asked for in production within the company i work at, they needed a higher resolution screenshot of a scene with selection outlines without rendering and fiddling with the scene or shaders.

It couild be added as a slider within the screenshot options you can see in my screenshot : like 1 is normal res and 2 is double resolution etc.
