The IMS Information display provides:

By default, the IMS Information display is shown in the "Detail" format. In this format, all PCBs are shown fully expanded. By instead selecting the "Summary" point-and-shoot field from the display header, PCBs are instead provided condensed in a table format, as in the example shown in Figure 5.
