Renaming parts while exporting assembly to a different 3D format

I need to export complexe assemblies to IGS. When I do, the individual parts are renamed to reflect the original model tree. The names of the various bodies then become super long. Is there any way to have SolidWorks rename those bodies with a sequential number, a random generated name of let's say 8 letters, or anything else then the default? I am exporting because I want to protect/hide the model tree. Could a macro do this renaming? Any suggestion is welcome.

Thanks,

Louise
