title: How to tell ReSharper to sort usings with system namespaces NOT at the top?
body: <p>Visual Studio has an option to place system directives at the top when sorting them.</p>
  
  <p><img src="https://i.stack.imgur.com/71HGg.png" alt="enter image description here"></p>
  
  <p>When this setting is <strong>unchecked</strong>, sorting using statements by right-clicking on them and using the <em>Organize Usings</em> feature, places System namespaces alphabetically along all other namespace imports.</p>
  
  <p>However, ReSharper does not seem to honor this setting, nor does it have anything similar on its own Namespace Imports options page.  It always behaves as if you want System namespaces at the top.  This is especially annoying when you already have some at the bottom and you let ReSharper suggest a namespace to import, then you end up with some at both ends of the list.</p>
  
  <p>Is there some way to fix this?  Or is this just a bug/oversight in ReSharper?</p>
