title: Change column names of a cube action as they appear in Visual Studio
body: <p>the title pretty much says it all.
  I have a cube with data in it and I have yet to find a way to change the column names.</p>
  
  <p>They appear in a very ugly manner like [cubeName].[$dimension.columnName].
  I have tried everything I know and anything I found on the web but nothing seems to be working.</p>
  
  <p>What I tried to do in most cases is create an Action in the Actions tab and write some MDX query language in there. No results whatsoever. As if the action is never run.</p>
  
  <p>Does anyone know how to do this? I've spent about 3 days trying to figure this out.
  Thank you.</p>
