Returning the state of an agregate service.

Hi all

I have 3 tests monitoring in one column. I want to have an AND condition where all the tests have to be true in order for the service to revert to green. At the moment the one server fails, I return a red, the next service works and the whole column gets returned to green. Is there any way to implement this without makeing 3 seperate columns?

Cheers
