Two questions related to custom channels because apparently I'm missing something obvious: (a) Any recommendations on how to build a channel that only contains posts by mutuals, regardless of protocol (AP, AT, Diaspora*)? I thought there'd be something like this by default but I fail to find it. And / or (b): I'm following a bunch of hashtags out here, as do I import posts for some hashtags from Tumblr and load my pinned feeds from Bluesky. Is there any way to make all these "non-follower" posts go to a custom channel to not flood the default network timeline? It's not that I do want to completely suppress them, otherwise I'd probably remove these subsccriptions, but I don't want them to be permanently around.
