Is there a way to make the item header in the timetable view as large as the whole duration of the item?

In other words, don't display the description area, but only the header. The reason, often the headertext is just too large to display in the small header area, so I would like to use the area of the descriptiontext.

Now, when I have an appointment that spans 5 cells. I have one small cell for the headertext and 4 emtpy cells.
