Direct file exchange between Cubase and WaveLab Pro 9

I have upgraded to WL Elements 9 and have both 32 bit and 64 bit versions installed. i notice that if I open a file from Cubase’s Audio menu into WaveLab, it opens up the 32 bit version of the Elements 9, even though my Windows default for .wav files is the 64 bit version.

Is there a preference somewhere to tell Cubase which version of WaveLab to use?
