It would be nice to be able to group a few tests together to create a "TestGroup" and then assign it to a test list. For example, we may want to create "temperature pressure correction" group (i.e. a trio of temperature, pressure and correction factor calculation). It would be really nice if you could just add this "group" to a test list instead of having to add three separate tests.
