Are Supermagazines a thing?

Apologies if this is obvious or already a feature (or if I'm doing this wrong, it's my first post), but is there a way to create supermagazines?

For example, I could create 1 "tech" folder on my profile that will show me everything from tech@kbin.social, technology@kbin.social, technology@beehaw.org, technology@lemmy.ml, etc... Then, with 1 click, I could see everything tech-related from all across the fediverse in 1 place. Then I could have another supermagazine for news, gaming, memes…

It would be so nice not to have to go to 3 magazines on different instances that all cover the same topic just to see everything and seems like interconnecting things would be agreeable with the fediverse philosophy. Heck, it’d be neat if I could just subscribe to 1 supermagazine for gaming and get everything without the fuss of adding each instance separately. It would also make the transition for new users much easier

Is this a thing?
