Need A Way To Reset The Global Resources On The Title Screen

So I was working on a custom UI resource pack, and I messed up pretty bad when I messed up the settings page and put the pack in global resources, and it was a pain to remove from the device, so I'm not going to try and get a screenshot.

 

There should be a way to reset the global resources, say, on the title screen, but not something that can easily be done by accident, or doesn't look good like a button on the screen. Maybe for controllers it could be something like hold ZL+ZR+Start+Y (LT+RT+Y+Start) on a controller, or CNTL+SHIFT+R+Backspace and after a couple seconds a hold duration bar could appear before resetting it or something like that. Touch idk at the moment
