Currently if I want to collate a report on events facilitated by a particular individual (or, say, run by a partner organisation, or any contact with a custom role), I have to go to each event from their contact record, or add each event title to the event 'is one of' filter - it's not possible to filter the event participant list report by a facilitator without limiting the data to that facilitator, and the other event reports (e.g. event summary) can't be filtered by an individual.
Is it possible to build a report to filter in this way? i.e. for a list of events filtered by one contact record, provide data on all event participants.
(I had considered just adding the facilitator as a custom contact reference field, but unfortunately that only allows me to add one contact per field, and there's sometimes more than one facilitator per event.)
