Yep, it’s in settings under the filter and blocks section. Just tried it myself. Make sure to use the same apostrophe as they do in their titles, I just copy pasted a title up to the work part. Or you could add a filter for the comic website.

People can easily make create a filter since OP uses the same title format for the posts ¯\_(ツ)_/¯
