Flexbox to the rescue!
Stick this in functions.php. Make sure to use your dev tools to make sure the classes are right. But basically, you use flexbox order property to rearrange items in the left admin sidebar.
add_action('admin_head', 'mytheme_custom_admin_css');
function mytheme_custom_admin_css() {
echo '';
}
