[Scripting Question] Resetting Self Switches on Every Map

[F14m3rz]

There was a helpful thread that explained how to reset the switches for the current map, but I wanted to know how use an event script to reset every self switch at once. I tried using a loop to use the code to work on every map, but apparently you can't use local variables within an event page without the game crashing. Is there any way I could do this without typing out every single map ID?
