No, you have to make them per instance, but its sorta redundant as each instance communicates with each other and displays the same content / can communicate with each other (example: You’re lemmy.sdf, The user below me is Beehaw, and I’m shi.tjust.works

While there are a few niche subreddits I’ll probably still periodically check in on the sites been going downhill for years now, and the most recent AMA / API tomfuckery made me jump ship to greener pastures.
