Draw PropertyDrawers in PropertyDrawers?

I have a Profile Class which right now has no custom editor. it holds a List. SkillGroup holds List and some stuff. Skill has some stuff (ints, enums)

Now I followed these tutorials to build a custom inspector for my skill, easy. Then by making my skillgroup into a monobehaviour, I was able to make a CustomEditor for it and had it draw the list of skills using their PropertyDrawer. Great. Now, SkillGroup shouldn't be a monobehaviour, and I want the customEditor to be for Profile, drawing all the skillgroups and skills and whatnot. So I'm trying to make a SkillGroup CustomDrawer, but I can't seem to draw the skill customDrawers. Here's what I got.

 [CustomPropertyDrawer(typeof(SkillGroup))]
 public class SkillGroupDrawer : PropertyDrawer
 {
     public override float GetPropertyHeight(SerializedProperty property, GUIContent label)
     {
         int lines = property.FindPropertyRelative("Skills").arraySize;
         return 16f + 18f + 18f + (18f * lines);
     }
 
     public override void OnGUI(Rect position, SerializedProperty property, GUIContent label)
     {
         int indent = EditorGUI.indentLevel;
         label = EditorGUI.BeginProperty(position, label, property);//tells the label this is a property, so stuff should have proper content menu
         position.height = 16f;
         //name
         EditorGUI.PropertyField(position, property.FindPropertyRelative("Name"), GUIContent.none);
         //skill label
         position.y += position.height;
         SerializedProperty list = property.FindPropertyRelative("Skills");
         EditorGUI.PropertyField(position, list);//Draws foldout, array name
         //size label
         position.y += position.height;
         SerializedProperty size = list.FindPropertyRelative("Array.size");//shows "special relative path" for Array.size, stores property        
         EditorGUI.PropertyField(position, size);//draw size field as serializesProperty
         //items
         EditorGUI.indentLevel++;
         for (int i = 0; i<list.arraySize; i++)//foreach item in list.array
         {
             position.y += position.height;
             //THIS NEXT LINE SHOULD DRAW THE PROPERTYDRAWER!
             EditorGUI.PropertyField(position, list.GetArrayElementAtIndex(i));//draw the item in the array
         }
         EditorGUI.indentLevel--;
         EditorGUI.EndProperty();
         EditorGUI.indentLevel = indent;//reset indent
     }
 }

end result should be:

• ProfileEditor

• profileName

• add'l profile info

• SkillGroups

  • skillGroupDrawer

  • GroupName

  • Skills

    • size

    • skillDrawer

    • skilldrawer

    • skilldrawer

  • skillGroupDrawer

  • GroupName

  • Skills

    • size

    • skillDrawer

    • skilldrawer

    • skilldrawer
