How to display more than 20 posts on wp-admin/edit.php

I googled for the answer for awhile. Upon inspection i did not find any settings but noticed that wp-admin/includes/post.php has a post_per_page variable. Hard coding was not good enough for me seeing as one update and the code can be gone forever.

function MultiEdit(){
update_user_option( get_current_user_id( ), 'edit_post_per_page', 20 ); //keeps the edit.php /post.php to 20 posts!
}
add_action('admin_head', 'MultiEdit');

I recommend that code can go inside your functions.php. A little description about it, basically from my understanding the post_per_page is stored per a username, if none exists it defaults to 20. You can change this number to 50, 500,5000 if you wish and it’ll do so.
