How to view posts from an entire instance?

Is there any way to view all posts on a given instance (as if that instance was your home instance and set to "local"), and not just a specific community/communities you are subscribed to?

Specifically, my home instance is Lemmygrad, but I'm interested in ttrpgs and want to keep up with ttrpg.network. This instance is relatively inactive so I never see their posts on my front page, and it's content is spread over several communities. I want to be able to see what's going on there while still using my Lemmygrad account.
