Section Keep Together
It would be great to be able to set a section such as the detail section, or a grouping to be kept together on the same page. This is helpful in the case where a section renders over multiple lines. For example, if a detail section spans 3 lines, it would not print at the bottom of the page unless the entire detail section fits. If it doesn't fit, it would go to the top of the next page. The same would hold for a grouping: if the whole grouping (including sub-groups and details) won't fit at the bottom of the page, then start at the beginning of the next page.
