Agree with much of what has been said, and thank you for it. But, the point is, that Boeing has offered the Abeam Points function as an added upgrade, presumably, to be a 1 button work saving method. By using all the piano playing you mention you are going back to the type of FMC that was in use years ago before the Abeam Points function was added. if we're not allowed to use it, or if it causes problems, then it is all a waste of an option and could be removed.
