The Past Conferences collection contains the sessions from past events including the speaker, date, time, abstract, and so on. Past Conferences is used for the Detail pages of Multi-Event dynamic pages. The /multi-events page is the index; each event’s page is /multi-events/, such as /multi-events/2020-fall-conference My intent is to copy the session info from Proposals to Past Conferences after the event and then delete them from Proposals. My thinking is to keep Proposals rather clean with only the current info and use Past Conferences only for previous sessions that were accepted (not all proposals).
