Hi Ben,
Great question! Event Calendar PRO includes the feature to create recurring events. In other words, that would allow you to create the same ongoing event.
However, Event Tickets Plus does not support recurring events at the moment. It is something we are working on but, in the meantime, limits things in such a way that the tickets created for the parent event in the recurring series is the ticket stock for all events in the series.
Sorry for the bad news, but does this at least help answer your question? Please let me know.
Thanks,
Geoff
