with Edit On, just click and drag the mouse cursor and draw a straight line for which current selected event values will align to it (and only those).
this applies to the event values pane (the one below the main piano-roll) so it's mostly about the second FR of yours.
tbh. I can't see the usefulness in drawing a straight line of notes in the main piano-roll (it doesn't make much musical sense to me, as to have yet another edit mode just for that really, but that's probably just me and my ignorance).
there already is one such tool...
