title: Call php artisan custom:command with an argument at the end without specifying the ones before
body: <p>Is there any way that if I have a command of this kind:</p>
  <pre><code>protected $signature = 'custom:command {arg1} {arg2} {arg3?} {arg4?} {arg5?}';
  </code></pre>
  <p>To call it without specifying arg4, but with arg5? Something like:</p>
  <pre><code>php artisan custom:command arg1_val arg2_val arg3_val arg5_val
  </code></pre>
  <p>Of course, if I do it like above arg5_val will be interpreted like arg4_val and arg5 will be ignored.</p>
  <p>I hope my question is clear and it was not answered already. Did not even have a clue how to search for it :))</p>
  <p>Thanks in advance!</p>
