title: Use Taxonomy Checkbox to add Custom Post Type to Main WordPress Loop & Feed
body: <p>I have a problem with WordPress Custom Post Types that I can't seem to wrap my head around.</p>
  
  <p>I would like to have a category or a custom taxonomy checkbox on my custom post type, and if this one is checked, then display the post in the WordPress main loop and in the WordPress feed.</p>
  
  <p>Note: I don't want to display all posts from my custom post type in the main loop and feed, only the ones that are checked.</p>
  
  <p>Is this even possible to achieve? I've tried to google for a solution, but with no luck so far.</p>
  
  <p>Thanks!</p>
