title: How do I selectively add parts of one project to another?
body: <p>I want the following items in this solution to be added to another solution: </p>
  
  <p><img src="https://i.stack.imgur.com/kD1IN.png" alt="Try to export"></p>
  
  <p>(the selected items are what I want to import)</p>
  
  <p>I select those items, and right click > copy, but when I go to paste the items, I can't paste anything:</p>
  
  <p><img src="https://i.stack.imgur.com/Ziwih.png" alt="Unable to paste"></p>
  
  <p>Is it possible to import just allowed.cs, theme.cs, theme2.cs, themebase.cs to EmailSpitter? I also want to copy everything in Allowed.cs (meaning the design and the code inside)</p>
  
  <p>I tried moving the items one at a time, but that didn't work either.</p>
