Is there a way to get the solidworks icons for use in an addin

the included icons in the swconst.swControlBitmapLabelType_e is pretty limited (no coordinate system, sketch, etc...) are there files for other icons stored somewhere or can I programmatically extract them from SolidWorks somehow?  Right now if I want to use one that is not in the enumeration I have to recreate it myself which is a huge waste of time since they have already been done before.  I've done some searching in the install folders for them but usually end up empty handed.
