Using new ILT Bulk Loader for loading historical records

Summary

If you load historical records for a past ILT event, does the system automatically send messages?

Wondering if anyone has used the new ILT Bulk Loader to load historical records for a past ILT event.  While we try to run most ILT events through our LMS, their are 'rogue' elements in our company that will host and administer an ILT event outside our LMS.  In the past, we retroactively create the session and then back-fill the participants.

I would like to use the Bulk Loader to do this but am concerned about it kicking off messages, like the User Approval message for example.  Don't want to unnecessarily confuse people.  FYI... Several messages, like the User Approval, are active at the global level so are automatically active when a new Enrollment is created.  (That's why I'm concerned.) Don't really want to de-activate them all at the global level if I can help it.
