Thread:Project:Support desk/How can I limit the Special:WantedPages range to only main space?

Currently my wiki have about 7000 articles, and their are some related article really need to be created. However, one of that wiki's editor use bot create tons of template, and these template sooo many uncreated links, which push all the real urgent pages to very back.

Therefore, I need to block all the wanted link created by templates to show pages that really need to be created. Are their any setting could limit the Special:WantedPages range to NS=0?
