Would love to be able to do that but can't.
Possible work arounds:
Put the extra text you wanted to put in the body into a tool tip. When you hover over a field in the body, the tool tip pops up and displays.
Put the extra or enlarged fields in a pop over.
Put the extra or enlarged fields on a different layout and add a button that you can click that opens a window with that layout to show the data.
Use a tab control or slider and put the extra or enlarged fields in their own panel.
Thanks Phil. Some creative solutions. Just tinkering around.
