Access Abstract Class Fields via Inspector

So i am trying to use a very basic sample to show what i am trying to figure out. Access to a list of common abstracted class with access to the properties within that list.

Here is a screenshot of the inspector without and with abstraction:

Also just to get the abstracted version to show i had to use MonoBehaviour as the base class. I did not need to do that in the standard class...

I know how to get a list of all the subsclasses of a specific abstract class... As in this list works but I have no access to any properties in the abstract list via the inspector like i do with the normal class.

What are my options along this pathway?

Thanks
