Not mocking a call within recording

I am doing some testing of a DAL and so am testing classes which effectively take in a load of data and then passing it out again.

At present I am doing this in roughly the style shown below.

       [TestMethod]
        public void Copying_Test()
        {                   
           VWE_STB_BOOKMARK entity = new VWE_STB_BOOKMARK();
           entity.STB_ID = int.MaxValue;
           Nullable<int> temp_STB_ID = entity.STB_ID;

            using (RecordExpectations recorder = RecorderManager.StartRecording())
            {
                VWE_STB_BOOKMARK newBookmark = new VWE_STB_BOOKMARK();
                recorder.ExpectAndReturn(newBookmark.STB_ID, temp_STB_ID);
            }
            try
            {
                VWE_STB_BOOKMARK target = new VWE_STB_BOOKMARK();
                Nullable<int> result = target.STB_ID;                
                Assert.AreEqual(temp_STB_ID,result);
                MockManager.Verify();
            }
            finally
            {                    
                MockManager.ClearAll();
            }
        }

I was wandering if there is a may to use the properties of an entity as the results from calls in natural typemocks. This would be something like the code shown below.

        [TestMethod]
        public void Copying_Test2()
        {                   
           VWE_STB_BOOKMARK entity = new VWE_STB_BOOKMARK();
           entity.STB_ID = int.MaxValue;
           Nullable<int> temp_STB_ID = entity.STB_ID;

            using (RecordExpectations recorder = RecorderManager.StartRecording())
            {
                VWE_STB_BOOKMARK newBookmark = new VWE_STB_BOOKMARK();
                recorder.ExpectAndReturn(newBookmark.STB_ID, [u]entity.STB_ID[/u]);
            }
            try
            {
                VWE_STB_BOOKMARK target = new VWE_STB_BOOKMARK();
                Nullable<int> result = target.STB_ID;                
                Assert.AreEqual(temp_STB_ID,result);
                MockManager.Verify();
            }
            finally
            {                    
                MockManager.ClearAll();
            }
        }

This wont work at present. Presumably as TypeMock is mocking the call to entity.STB_ID within the recording section.

Thanks,
