You can filter your participants in the participant list view by selecting one of your saved filters. You can find your saved filters in the advanced search bar. Once you have selected a filter, this one will be applied to your event list page and will only feature the events that match the filter.
A new filter can be added by clicking on the Add new filter button. The popup will appear where you add filter name as well as criteria. You can easily add as many as you want and remove them as well. In this example below, we want to create a filter for all of the media outlets who applied to be on the event but only those who we have reviewed. That means we will need two criteria items, based on two fields: Participant type which needs to be set as Press and the field Reviewed which needs to be checked as yes.
