How to implement in wordpress the ability to write entries to specific pages?
Perhaps I did not understand the essence of the question, but I will try to answer. Entries do not obey pages, entries are subject to categories (categories). But you can do it manually. You create a page and after the entry is published, you link to this entry on this page. See the example "Village with links to records." It turns out that all site records are collected on one page.
Options-> Read-> Specify "Static Page"
