Idea: add notes to meetups

When I organised a meetup a few weeks ago, we got a table but then couldn't figure out how to tell RSVPs where to find us (what name is the table reserved for), other than posting to the telegram channel where only some RSVPs could see.

Maybe there could be a way to dynamically add notes to the event?

Looks like some events have a tg link, maybe I missed this while setting up the event originally, but I'd like to be able to add this, or a note, after making the event.
