how to assing multiple std::tuple_element as function arguments using variadic size_t templates

I want to create a function that changes multiple values inside a tuple with one call.

template<class... Args>
class EventN {
public:
  std::tuple<Args...> mArgs;

  EventN(Args... args) : mArgs(args) {}
  EventN() {}

  template<size_t N> void set(typename std::tuple_element<N-1,Tuple>::type value) {
     std::get<N-1>(mArgs) = value; //I use N-1, to start from '1'
  }

};

The set function above works as I expect it to:

auto event = new EventN<String,int>();
event->set<1>("testEvent");
event->set<2>(12);

Now, I want to extend the function to:

event->set<1,2>("testEvent", 12);

How can I achieve that? Is there a way to make std::tuple_element<N-1,Tuple>::type variadic?
