Where do Config files get packaged to when they are included with +AllowedConfigFiles=?

Hi,
I want to be able to edit config files once the game has been packaged, I have included my DefaultCustomsSettings.ini with +AllowedConfigFiles= in DefaultGame.ini, but I am wondering if the config file gets copied / packaged into the game directory, and if so, where to?

The config is definitely being loaded as the variables are available, but I cant seem to find the location they are being pulled from.

thanks
