Hey Stephen,
Thank you for reaching out to us!
It’s certainly possible, but remains something that we do not support “out of the box”: some amount of custom dev work would be required to make this happen.
I would recommend up-voting this feature in our User Voice page to give us an idea of how much demand there might be:

We have a customer who recommended using a third-party plugin to achieve what you want, but for Community Events. We didn’t test it, but perhaps this alternative can help you as well:
How to trigger email notifications to the event organiser in Community Events
If you have any other questions at all please feel free to let me know and I’d be happy to help as best I can!
Thanks!
Patricia
