Is it possible to add a menu to a post/page in WP?

Question

PHP

I'm making a site on wp, there are 20 pages on the same set of links, almost one more menu.
How can I display it beautifully on these pages so as not to prescribe it in the body of each page in the admin panel?
mb in page.php to register? but I have a lot of pages WITHOUT such a menu, and a lot of pages WITH it, so I don’t know how to separate them (not list them in get_permalink).
can anyone have any ideas?

You can create a separate template for pages where you need a menu
