Hi - i'm not sure you could use BAT to update them in bulk but I think what you can do is export the translation and route patterns using BAT, then open them in excel and bulk change from there. Then you can import them again. Although you will probably have to delete all the current tranlations/route patterns before importing the new ones. Not something to be done in production time.
Not sure if this is the only or most efficient way of doing it but I'm sure someone else will chip in with some pointers.
Hope that helps,
Neil
