How to override or add OnTriggerEnter()

One object has two collider and one script.
I want to operate OnTriggerEnter by one script.

ex)
Collider a = GetComponentInChildren();
a.??? += MyFunc;
Collider b = GetCoponentInChildren();
b.??? += MyFunc2;

Is this possible?

You will need to have each collider in a different GameObject, and attach a component with a OnTriggerEnter() method to each of these objects.

OnTriggerEnter does not differentiate the trigger collider that got hit.
