Engine Scalability Settings - Custom Presets

The current presets are good (low->cinematic), but I would love the ability to save some of my own. Depending on what I’m working on I might have nearly everything set to low except one or two things set just high enough to give feedback on what I’m working on. Currently I’m working on a very heavy forest level, and while working to add some hand-placed lights, i have everything turned to low except post processing (med) and shadows (high). I can easily imagine other scenarios where a custom preset would be useful.

Not sure where to best place to add it - idealy it would be right under ‘monitor engine performance’, with a ‘save current as custom preset’ and a list of current presets.
