I was wondering if there was a way to overwrite a file with the same name when exporting versions instead of Aperture automatically appending a number to the file name?

For example:

I export a picture named "PICT001.jpg", I go back and make different adjustments to the same picture and I want to export it again to the same folder and filename. Currently, Aperture will name the new exported file something like "PICT001(1).jpg" instead of just overwriting "PICT001.jpg"

Your help is greatly appreciated.
