Hooks for after event import?

I’ve searched the documentation and haven’t seen this, but are there any hooks available to change the behavior of the plugin after an event is imported, but before it’s saved?

Specifically I want to prevent the creation of new event locations in Event Manager, or better yet add some logic to look for a matching location first. Right now importing seems to create a new location for each imported event, which creates a lot of manual cleanup to do after. I’d also like to be able to set some custom fields, etc.

Thanks,
David
