Work-around method. This approach won't work in the Hit Point tracker that makes the bar-graphs over a token. In the Character Sheet, in the BIO section (free text block area), simply type: (Example) HIT POINTS: MAX HIT POINTS: 12 WOUNDS or CURRENT HP: 12, 7, 2, 11, 9, 6, 1, 12, etc. The last number you typed in the list is your current hit points. The comma-delimited numbers are all your past HP statuses. Same way I keep track of it on paper character sheets since the old days.
