Question: Could I transter my neuron id to antoher NNS account?

If it is YES, how to.
If it is NO, Is there any plan to implement this feature?

AFAIK no, there is no way to do this, and nothing planned. Reasoning given was that it would lead to neuron markets, which defeats the whole purpose of the lock-up period, which guarantees some long-term vision on the voters’ part.
