FEATURE REQUEST -> It would be great to have the option of which GPU to use similar to Blender

I currently have a GTX 980 and RTX 2080ti installed in my machine. I’ve been trying to get UE4 to utilise my RTX card but all the solutions I’ve found on the internet either using Windows graphics settings or nVidia control panel do not work for me. In both cases the options available to me are not the same as those in the step by step guides.
It would be great if there was a simple check box to tell UE4 which GPU to use in the same was that I can do in the Blender hardware options.
This seems like an issue that many others would also benefit from given the number of posts I’ve seen regarding similar in the unreal forums.
Hope we can get this soon!
