I think if you wanted to see mostly 'grad content from .ML, you'd need to subscribe to only (or mostly) 'grad communities, then sort by "subscribed".
I usually sort by "local" to see the stuff here, and I find that pretty convenient.
Jerboa, at least, has a pretty convenient mechanic for switching between Lemmy accounts, so it wouldn't be hard to just have two accounts for different purposes.
I've got a midwest.social account I use just to see what's up with the part of the fediverse that blocks us.
