Try this ....
Go to the audiobank and copy the Zombie folder .....
Call it zombie2
put your wav file in calling it ..... zombie_groan_male.wav
Click properties on the clown and go to the soundset currently set to .....................audiobank\zombies\zombie_groan_male.wav
Do not browse to your new folder .... Simply edit the text adding the number 2 ....audiobank\zombies2\zombie_groan_male.wav
The same can be done for sound1
I just tried this and it seemed to work ...
And if there is an update you only have to point to the folder again without overwriting your new .wav files
