How do I override the font for a summary?

summ = grid.DisplayLayout.Bands(0).Summaries.Add("SummaryName", SummaryType.Sum, _
                    grid.DisplayLayout.Bands(0).Columns("Test"))
summ.Appearance.BackColor = Drawing.Color.LightYellow
summ.Appearance.BorderColor = Drawing.Color.LightGray

 I can change the bordercolor, backcolor, but how do I set the font?

 I want the summary to have the same font as the grid above it.

Thanks.
