Exclude object from GI

Hi guys,

Just a quick one about Corona render which I consider very powerful but few tools are missing from my point of view.
One of these,but maybe I am wrong and I hope so, is that there is no way to exclude an object from the GI, I remember you could do it in Mr and Vray but I am not finding anything like this in Corona, do you know if it’s possible and how do it?

Thanks

Dan
