Split a Wordpress entry into pages, how to change the cnc?

Question

PHP

Good!
I've paginated the post, here's a test site for an example .
The main address of the page looks like this: site.ru/razbivaem-zapis-na-stranicy
And the links to the pages are like this:
site.ru/razbivaem-zapis-na-stranicy/1
site.ru/razbivaem-zapis-na-stranicy/ 2 etc.
How to make CNC for entry pages by name? Something like this:
site.ru/razbivaem-zapis-na-stranicy/page1
site.ru/razbivaem-zapis-na-stranicy/kak
PS: The name of the page, I specify it myself when adding it, it is shown on the site, but not in the address, help set up.
Thanks in advance!

Answer 1

did not try to create "page" and "subpages" separately in the admin panel? In the subpage settings, specify "page" as the parent.
