@truback Not that I am aware of just yet.
With that said, I would keep watching... I suspect that before too long the IR/poli sci community will spin up their own mastodon instance. Much like mastodon.pawprofs.org, or econtwitter.net (which despite the name is a mastodon instance).
Once it exists, you can either join it to easily monitor the local timeline (some people keep second accounts for this), or you can do what I do and simply click through posts from there to see who is being @'d.
Just make sure you choose "Merge" when importing a "following" list. Otherwise you'll lose the current people you follow.
It's also worth spot-checking to make sure the imported names are actually being followed after a few hours. I've been having long delays and sometimes I end up just following people manually out of impatience.
You can download it here and bulk-follow accounts: https://brentonpeterson.github.io/Mastodon-PoliScientists/
