How to animate a stove ?? Problem

Hello!  I have this problem. I was trying to change the animation of how the food from the oven gets out. The normal way is that sims put the food in the oven in a front-back position and i want to change the animation into upside-down. Is it possible??  I dont know where or what need to change. I saw the tuning of the stoves and their make_recipes tuning if see how to change that. but nothing. Perhaps changing a statemachine ? but dont know where is controlled the animation of the food in the oven. I use the schmapple oven as a base , but any stove will work. Please light me up. =p
