How do you include the event details in a report (xls or pdf) ?

Hello, new to using CA (v 6.9.4 / build 9177) to audit our AD env.

Currently, working on a report for group membership changes. The layout options tab seem limited, and I can't figure out how to include the "What" details (eg, user1 was added to group group2 as a direct member).

So, my question is - How do you include the event details in a report (xls or pdf) ?
