speedpak bom PDM 

I'm using speedpak configurations on some subassemblies. I want these speedpak'd subassemblies to not show their child components in the PDM BOM. I've tried making the parent configuration have the "don't show child components" property but that doesn't seem to flow down to the speedpak and there is no option in the speedpak configuration for it. Is this something that is possible
