attrs file

I have a need on one of my radius servers to pass every reply attribute my realms I proxy for send up to me regardless of what they are. I then pass these replies upstream. Everything I read describing the default 'realm' in the attrs file mention adding attributes I want to pass on. However in this one instance I would have to list every dictionary attribute. Is there not a way to tell radius to pass everything, maybe with a * on a single line or maybe nothing in the default section? Or must I list every single one? -- Chuck
