How do I deal with "fractured" communities? - Lemmy.world

One of the biggest issues I’m having trouble getting past with Lemmy is not knowing which communities to subscribe to. An example, if there are like 10+ different communities for “technology”, do I really have to subscribe to all of them just to get the same experience I would have gotten on /r/technology? Is there a way to “clump” these communities together so I can just subscribe to one “multi-community” that houses the posts from all of them?
