Can the Order Import Utility include Initiators?

For our Grand Tier dinner and performance events, we enter attendees in a single House Order for the performance.  This can mean entering 40-50 initiators in a single order.  

Much of the import data for the initiators is already coded in the Activity Table so it would save a lot of duplicate data entry if  the Order Import Utility be used to create this order.  

Thanks- Leslie
