is this in oblivion or skyrim?... im pretty sure it can be done, but it might be hard coded to the engine if you cant find it in the regular scripts for the game, there are also a ton of scripts that dont show up normally too (you are probably already aware of this stuff, just trying to cover the basics) if it is hard coded you can make small workaround mods using custom scripts (script extender is good for this) to sort of reverse or bipass the code. it also depends on how the engine handles the event... thats about as much usefull info that i have for the time being lol hope it helps some.
