This comes up fairly frequently and we are interested in solving the problem, but it's not currently technically feasible. See e.g. Paramaterised Suites? - #2 by grynspan . Actually, that's probably not a great example as that thread deals with a different definition of "parameterized suite." 
Anyway… today, syntax-based macros are not able to give us enough context to correctly expand @Test within a parameterized suite type.
