Use his report to see all the different meetings that group members have attended, including for other ministries or campuses.
There are two formats you can pick from when exporting a group: CSV and Web Page Format. CSV will export all people in the group, and their meeting attendance to a simple spreadsheet that you can use in Microsoft Excel and many other programs. The Web Page format will display all the group members in tabular format, which is handy if you want to print the report quickly.
