Is there a way to subscribe to all communities with the same name? - Lemmy.world

Is it possible to automatically subscribe to all (federated) communities with the same name? Example in the screenshot: I want to follow !astronomy, and I don’t really care whether the content is coming from from Lemmy.World, kbin.social and mander.xyz - I just want to see it all. Obviously I could manually subscribe to them all, but is it possible to do so automatically? Ideally if a new similar community pops up on another instance, I wouldn’t miss it. I read here [https://github.com/LemmyNet/lemmy/issues/3071] that community grouping is a thing, so that instances with identical communities can work together. Is that a feature that could work towards this end?
