Entities are only only part of a series once (are there exceptions?). When I want to add all release groups with a specific name to a series I keep finding releases I already included. So it does get difficult to find the ones that are missing.

Example:
https://musicbrainz.org/series/07aef939-6fe4-4933-a361-60edde7893d8

There are like one hundred something releases in that series. At least most, if not all have "Cold Hands Seduction" in the name. I want to add all to the series, but after adding the first page of search results it does get difficult to add the other ones since I keep having the search result cluttered with releases I already added.
