Trigger - Cliff reduction?

Trigger - Cliff reduction?

Does a trigger-action which reduces cliff height exist?
If it does I can't find it, and i desparately need one for my Helm's Deep map, otherwise i'll need to replace most of the wall with bridge sections and ...

Thanks for help

nope you must justreplace a part with a bridge and let that part be removed....

well uhh it wont look to cool but instead of lowering the cliff u can create a foot switch on the cliff (they are walkable over cliffs and in water etc.) depends on how you do it to make it look better but dont really know much else...
