You can select the number of generations to display on the report. Select the Up or Down icons to increase or decrease the number of generations. You can also add additional facts to the report using the "Items to Include" icon in the report section of the program. I use FTM's reports although there are some limitations with respect to images, etc. Many of my books are over 2,000 pages for single descendant lines.
I can send you an example if you are interested.
