No, this is not possible. There isn’t a way in WP to create a page for a specific repeater value.
You should have (maybe you already do) a custom post type for projects. You’d then show the list of projects on the projects archive page and then individual projects on the single project page.
See https://developer.wordpress.org/themes/basics/template-hierarchy/ and https://codex.wordpress.org/Post_Types#Custom_Post_Types
