(Feature suggestion) Make a text channel for people who are interested in an event

Hello!

I have a suggestion for the Event feature of community servers.
I often make scheduled events for IRL events on my Community Discord server, and I always make a text channel for people that are interested in said events to discuss the event and make plans. This is quite a tedious process, since quite often there are 30+ people interested, and they all have to be added to the text channel manually.

My suggestion is that server admins could create text channels for events, where users who have marked themselves as interested in the event would be added automatically. This would make the process of creating channels for events, and discussing the event much simpler and more user friendly.

Thanks for reading my suggestion!
