Combine fields of two object arrays in the inspector

Unity Engine
1

Good day!
Help me to combine the fields of two object arrays in the inspector.

I have a class (EntityParent) with an array of objects (EntityParentProps) that contain properties.
Then the class needs to inherit (EntityChild) and add new fields (EntityChildProps)

public class EntityParent : MonoBehaviour
{
   [System.Serializable] public class EntityParentProps {
       [SerializeField] string field1;
    }
    [SerializeField] EntityParentProps[] entityParentProps ;
}

public class EntityChild : EntityParent
{
   [System.Serializable] public class EntityChildProps {
       [SerializeField] int field2;
    }
    [SerializeField] EntityChildProps[] entityChildProps;
}

The EntityChild class arrays are displayed separately in the inspector

Is there any way to combine the elements of an array so that they are displayed like this

Yes, you can serialize structs (or classes) using System.Serialize.
Then simply make an array of said struct or class
