Multi-resource events and dmMultiResource Mode

I am attempting to use DBPlanner with multiple resources for a single event. Is it possible to somehow override the dmMultiResource mode of TDBDaySource so that the event is duplicated on the planner for each resource it is assigned?

There is a 1-1 relationship between events on the Planner and records in the database and 1-1 relationship with an event and a resource. So, if something is connected to multiple resources, it should be represented by multiple PlannerItems.
