Calling a property editor from my component editor

My component has a property that's a descendent of TCollection.  The
property editor for TCollection works great; however, I'd like to call this
property editor from my component editor.  I'd imagine all I'd need is to
create an instance of the TCollection property editor BUT I can't find where
it is...any clues or suggestions?

TIA
