I know that one can edit search criteria when using "Find Participants." When I edited the criteria for participant role, I checked the boxes for "attendee" and "presenter", hoping to get only those people for whom both statuses apply. (Some attendees are also presenters, but not all presenters are attendees.)  Instead, I get all those results for which either status applies.

Is there some way to construct a URL to give me only those people with both statuses?  They show up in the underlying database with a role_id of "12".
