Event attendees as Email audience option

Most of our Community events are virtual, so our Events listings are set up as External Events. However, our in-person meetups use the Community Event option. It would be really helpful to be able to easily message registrants with Know Before You Go or follow-up information. At the very least, being able to create a user segment based on registration for a particular event. 

Based on this thread, there’s a significant workaround or lift required to do that currently; it would not be sustainable for us to use a custom role or badge for every in-person event. Currently, we’re exporting the attendee list and email them from a separate platform, but that creates an inconsistent experience and isn’t as efficient. 

Thanks for considering!
