Is it possible to use add_submenu_page() to add an item that's a link to edit another page?

Question

I've recently discovered add_submenu_page and was pleased to be able to add my own page under a specific post type. I'm using a callback function to output some HTML directly

/**
 * Display callback for the submenu page.
 */
function homeslides_ref_page_callback() { 
?><h1>Curate Social Media</h1> 
<iframe style="width:100%; height:100%;min-height:600px" src="/mypage">    </iframe>
<?php
}

I would now like to make a separate callback for other custom post types, but one that lets me effectively make a shortcut to edit a particular page. For example, I have a custom post type called Careers, and within Careers I'd like to add a menu item that links to the edit page for a separate page.

It's not immediately obvious to me how I'd do this - does anyone have experience of this?

jQuery(document).ready( function($) {      
    $('#toplevel_page_display_strategies ul li:nth-child(3)').addClass('current')
    $('#toplevel_page_display_strategies').removeClass('wp-not-current-submenu')
    $('#toplevel_page_display_strategies').addClass('wp-has-current-submenu')

} );
