Custom Badges Per Server

I think it would be neat if we could create badges for server members similar to the Discord Nitro/Early Supporter/Hype Squad etc ones.

Even if it's preset badges you guys provide but let us label on the server. For example if we have members that participate in a Halloween event, they could earn a badge that says, "Halloween 2020 Participant" or something of the sort. My argument against the idea of just using roles for this is that for very active communities this gets cluttered fast. Especially with many events each year.
