c# on nested property change tracking

I have a generic class with a single argument that represents an Element of a third party DLL for the purpose of serialization of objects of T kind. What I would like to do is add a 'Dirty' map to my class and lazily trigger it whenever one of my Element's nested properties are changed.

Is it possible to when the property is accessed catch the request and identify what property is changing? That if a SET is being performed I can log that sub-property P is now dirty and needs to be saved? Or at least a single bit that indicates that SOMETHING has changed?

  public class ResourceSerializer<T>
  where T : Base, new()
  {
   T element;
   Dictionary<String,Boolean> dirtyMap;

   public T Element { get { return this.getElement(); } }
   public Boolean IsDirty { get; private set; }

   public ResourceSerializer()
   {
     dirtyMap = new Dictionary<string,bool>();
     element = new T();
     // code to reflect back upon T's Properties and build out the dirtyMap. 
     // I already can do this I just omitted it.
     // in my Person example there would be keys:  'FirstName', 'LastName', 'Age', 'Gender', 'PrimaryAddress'
    }


   // how can I call this programmatically?
   void flagDirty(String property)
   {
     dirtyMap[property] = true;
     this.IsDirty = true;
   }
   T getElement()
   {
     // In case I need to do a thing before returning the element. 
     // Not relevant to the question at hand.
     return this.element;
   }
 }

a somewhat advanced example of 'Base'. You can see how I need to recurse my actions as not everything is a primitive. I have a manager level class that logs all of these ResourceSerializer objects.

 public class Base
 {
   public Base()
   {

   }
 }
 public enum gender
 {
   Male,
   Female,
   Other,
   Unspecified,
 }
  public class Address : Base
 {
   public String Street { get; set; }
   public String State { get; set; }
   public String Zip { get; set; }
   public Address() : base()
   {

   }
 }
 public class Person : Base
 {
   public String FirstName { get; set; }
   public String LastName { get; set; }
   public Int16 Age { get; set; }
   public gender Gender { get; set; }
   public Address PrimaryAddress { get; set; }
   public Person() : base()
   {

   }
 }
 public class Patient : Person
 {
   public Person PrimaryContact { get; set; }
   public Patient() : base()
   {

   }
 }

and a small class i would turn into a test method later..

  public class DoThing
  {
    public DoThing()
    {
      ResourceSerializer<Person> person = new ResourceSerializer<Person>();
      person.Element.Age = 13; // catch this and mark 'Age' as dirty.
    }
  }
