What you need is a "blue Pen". (Back in the old days we didn't use blue ink because the early photocopy machines could not copy blue.) I had a lot of forms and the original had "Original, do not use" in large blue letters. You could make a nice photocopy, (it was after all the original) but you wouldn't use the original to write on, 'cause it said not to.
If we had a sort of "verbal font" different color and style, that could NEVER be a part of the permanent record you would be set. Then we could all work on a set of templates, "Jerk", "Moron", "dim-wit" etc.
(In the very very old days, the nurses hospital notes were easy to distinguish because the day shift charted black ink, nights Red, and Midnight to 8:00 AM charted in blue. Then the lawyers started photocopying charts and we all had to write with black ink)
