specify path problem with 2008

I have a problem with the 2008 version
In the 2006 version when we added a new part to an assemblysolidworks fired the event sldworks_PromptForFilenameNotify.
In 2008 not unleashes this event, but allows you to save, throughan entirely different form the part.
Now I t need to capture and change with my custom form, the folderbrowser that appears when you click 'specify path'.

is it possible ?

thanks,
