Just make a cell with the "prizes" token in it. Display it the entire tourney like many folks do (or after a certain level, or whenever you want to). The prize amounts will update as people rebuy or add-on or buy-in.
The prize cell should be part of the standard "toolbox" on the right side of the layout screen. So it is already set up to add that cell to your layout easily.
I would say a bulk of the people who use this program include this cell in their layout for the entire tourney so participants can see the prize structure all along.
