Requesting help utilizing resources.load to auto assign rigidbody variable in a class list

I've got a class:

 public class ObjectFrequency
 {
     public Rigidbody prefab;

     [HideInInspector]
     public float percentageChance;
     public float weight;
 }
 

and this list:

    public List<ObjectFrequency> prefabList = new List<ObjectFrequency>();

In the past I was manually adding the items to the list, but this is cumbersome and impractical. I would like to use resource.load to load all of my prefabs and add them to a list using my class. They will be stored in the rigidbody prefab variable. The other variables will be calculated and added automatically.

The part I am unsure about is auto assigning the prefab variable based on the prefabs that are loaded. Any tips would be appreciated.
