SimpleMDE custom config

Hello,

I'm able to add custom configurations to Redactor and MarkItUp, but not SimpleMDE:

Perch.UserConfig.redactor = function(){
  // redactor config works
}();

Perch.UserConfig.markitup = function(){
  // markitup config works
}();

Perch.UserConfig.simplemde = function(){
  // simplemde config doesn't work
}();

It seems Perch doesn't check for Perch.UserConfig.simplemde and always uses the default config.

Thanks
