Search for individual episodes and season packs equally on adding a new series

Certain indexers that I use tend to only have individual episodes rather than season packs. One of these indexers is my highest preferred, but because Sonarr seems to search first for season packs and only resorts to individual episodes if none are found, this indexer rarely gets used when adding shows with existing seasons. It would be great if there was a way to configure Sonarr to search for season packs and individual episodes with equal priority without having to do an interactive search.

Season searches include individual episodes

Unless your indexer returns poor results and fails to treat individual episodes as part of the season
