Need help with elevator levels

K, I know that there were lots of topics about elevators, but I couldn't find any solution to my problem there. So here it is:

We all know that elevators are just models with three stand animations, which are used on different elevation levels ingame and WC3 uses top plane of the model to determine the pathing. I use custom elevator models in my map, and so:
How can I make elevators with more than 3 elevation levels?
I make a model with 4 stand animations (using Stand fourth for the last one), but the game doesnt want to use more than three of them.

Any help appreciated. Kindly yours Van Damm

sry for posting, I've already found an answer myself. Plz close/delete the topic
