An invisible note with no value that can be placed anywhere on a staff?

I add a grace note after and make it invisible then tie from the main to grace note for skipping the first then grace note before in the second ending. I'm not use why you need it for articulations. Text will go on rests, so you can use either symbols or text special characters (press F2 dduring text entry) for articulations. Slurs work like ties of course.
