How to add steering wheel rotation to Chaos Vehicle (which is set up based on City Sample)

I recently finished setting up my vehicle - based off Chaos Vehicles, and also I managed to bring in all the destructible vehicles setup from City Sample.
Even when you look at City Sample itself, when the driver drives the car, the steering wheel doesn’t rotate.

The solution seems pretty simple - just get a “transform bone” in Animation Blueprint. But the main issue is, City Sample actually starts the vehicle as a much more simplified Skeletal Mesh which does NOT have any steering wheel bone. Once you do collision, the system switches to the much more detailed skeletal mesh which has the steering wheel bone.

I know this seems very particular issue - but I wonder if anyone can think of anything or has dealt with this situation before?

Do I need to re-setup this skeletal mesh and potentially add an additional bone for steering wheel? (and then “attach component to component” the Steering wheel mesh to the bone in this updated simplified skeleton?

Might be easiest to just remove the mesh (topology) for the steering wheel and add a separate component (with attached mesh) as a stand-in, sort of like what is done for swapping body parts (clothing) or dismemberment. Probably not the best method but you wouldn’t need to change the skeleton, just cut away that one section of the mesh.
