My specific request is to have a way to add a series with the Plex TV agent that if the agent does not match online sources, it defaults to the local metadata for Episode name, description, and date, if they are present.
This would allow me to add a completely customized or personal TV series, with full local metadata. There must be a way to edit the Plex TV trigger this fully local behavior. Ideally, it could be something analogous to the Extended Personal Media Show customized Plex agent.
