If you setup the code for custom filter ure_restrict_edit_post_type (I gave the link above) to exclude events from the edit restrictions, user will have access to all events without restrictions. It does not depend from post ID list in the edit restrictions form.
You just need:
1) replace ‘editor’ with your own role ID, let it be ‘role_a’;
2) replace ‘post’ with valid custom post type for events, let it be for this example: ‘event’.
So instead of


  if ( in_array( 'editor', $user->roles ) ) {
      if ( $post_type==='post' ) {
	   $restrict_it = false;
      }
  }

your code will have


  if ( in_array( 'role_a', $user->roles ) ) {
      if ( $post_type==='event' ) {
	   $restrict_it = false;
      }
  }

In assumption that you made all correctly, you can input post ID list after that and check that all events are still available for the role.
