I'm developing a structure of pages and sub-pages in Wordpress, but it is difficult and time-consuming because they are on average 100 sub pages and more on average 50 to 100 sub pages of the sub page, and it is exhaustive, plugin to batch all this sub page volume at once? I saw one that only adds to the page level, I need one where I can insert also at the sub page level for parent page, there are more than 60,000 entries and I can not find a suitable plugin for that.
