I don't think this functionality is available in perf..I could be wrong.. I think you would have to add a small piece of code in perf stat to achieve this.. Follow the execution from cmd_stat until run_perf_stat(I think..)
I will try to answer your question better once I go back to my lab..I don't have access to the kernel sources currently..
