Kind of like a multireddit but it shows up in my subscriptions as one community.

It would be nice if say I am subscribed to technology@beehaw.org, Technology@lemmy.ml, and Technology@kbin.social.

Is there a way that I can see all 3 communities in one thread just for me?

like it could be technology@$MY_USERNAME and I could choose which communities go in this multicommunity?
