How to Identify if a part has part family

I'm new to the topic "NX- Part family". I have a scenarion in NX 9.0,. I have created a part family to model1.prt, and named them as pattern_1, pattern_2, pattern_3, and  pattern_4.

Part family is now created and saved with default settings.

But when I open the base part (model_1.prt), it is not showing the part families list
(In Pro-E if any part families' base model is loaded it gives a list of child part names. I was expecting a similar kind.)

My question is, Unless checking the details in part family options, How else could I make sure whether a loaded part has part family in it.

Thanks
