Reviewing activities on a 2-page CV

I’m a big fan of 2-page CV, but in the most recent template I have received from a funder, they also ask to list reviewing activities. On the one hand, I appreciate that they try to acknowledge reviewing activities, on the other hand, I wonder what selection criteria would be appropriate — listing everything would fill most of the 2 pages (and still not tell us much about the quality of the reviews); only listing activities for “prestigious” work kind of defeats the point of trying to acknowledge the less glorious parts of what we do.
