[Vantage 8.03.403] Where Used App

When right clicking on a part in Part Entry you have the ablility to
open a "Where Used" app. It is a vantage form that quickly gives you
where used one level at a time, and you can dynamically move up and
down levels. The only problem is that it only is available in Part
Entry and NOT in Part Tracker. When i open the where used in
developer mode it says it is located in App.PartEntry.WhereUsed. It
is not a menu item anywhere within vantage. Is there a way i can use a
customization to call this Form from Part Tracker?
