How can I access the array index of a UCX element?

There are actually two questions:

  1. Is there a way to access the array of custom UCX elements of a static mesh?

and

  1. Can collision or a trace get back the index of the specific UCX element involved and how?

Here’s what I’m trying to do: Upon begin play I want a vehicle to go through all of its UCX colliders and designate each index as a section. Then each section gets checked for its neighbors and those are linked to each other. This will help multiple systems to be able to check, if they can interact with eachother.
Then when a UCX collider is hit or influenced, the respective section gets notified and affected systems can be called and for instance be turned off.

I understand that in a skeletal mesh bones can be used as “hit areas”, but the resulting colliders do not have the necessary shape I need for this. Unless there is a better way?
