Feature request: compatibility with Verbb Events plugin

[KatieMFritz]

I'm using https://github.com/verbb/events for events and sessions. Each event can have many sessions. I'd love to be able to set up two-way linking between them.

Hello! Is this something you need to do on your end, or does Josh need to do something as well? I created an issue on the Events repo too.

This would be my responsibility now! Looks like there's lots of other element types to add support for, so I'll review that.
