title: Office add-in ribbons: same tab with 2 addins
body: <p>I'm trying to make two word add-ins' groups to appear in the same tab (Tools) but they both create unique tabs (there's two 'Tools' tabs).  I <a href="http://channel9.msdn.com/Blogs/jwiese/Adding-Controls-to-the-Same-Tab-Group-from-Multiple-Add-ins">saw this video</a> but I'm using the Visual Designer, not XML.   </p>
  
  <p>Can I edit the designer code in some way to make this work?</p>
