Is there a way to block a community without going to it's page?

Hi, I am new to Lemmy and I just need help with something kinda QoL-ish. Is it possible to look at a post on the homepage IE http://lemmy.ca, and block the community it is coming from?

I don't want to have to manually click on the community and go to its page every time I want to block one. Is there like an extension or a specific UI mode that lets you do this? Thanks!
