PhysX and Contact Modification?

Hi,
According to this article:
Contact Modification
https://developer.nvidia.com/sites/default/files/akamai/physx/Docs/Callbacks.html

It is possible to preprocess generated contactpoints and even modify them. This allows the programmer to calculate virtual holes within a solid wall. As i am working on a PortalSystem, that’s what i need. However i have no clue on how to access this from UE4 atm. Do i have to go down the rabbit hole, or is there something i can use to access this without to much work?
