Is there any way to acquire a material ID pass through a refractive object but have the refractive object not contribute its ID colour?

I have objects inside a glass but obviously when enabling a Mat ID pass the glass also renders its ID, blocking everything - turning off the glass doesn't get you an ID pass that aligns with the beauty pass due to the refraction distortion.

I guess its not possible to make it work?

I can do it manually, but its a PIA to set up.
