Maybe you could add a new field for probability at target idx, such as:

public List<List<List>> Output; // (beam_size, batch_size, seq_len)
public List<List<List>> ProbAtOutputIdx; // (beam_size, batch_size, seq_len)

Yes, I figured you would have a good idea on adding something. I'll see about adding it.
