Is there a way to access a state through its ID?

Is there a way to access the state through its ID?
Instead of using access, I'm wondering if I can use something similar to access<STATE_ID> ?

It's doable with a simple wrapper, e.g.:

struct StateBase {};

struct A
	: FSM::StateT<StateBase>
{};

struct B
	: FSM::StateT<StateBase>
{};

StateBase& access(FSM::Instance& instance, const hfsm2::StateID id) {
	switch (id) {
	case FSM::Instance::stateId<A>():
		return instance.access<A>();
		break;
	case FSM::Instance::stateId<B>():
		return instance.access<B>();
		break;
	default:
		/* ... */
	}
}
