Yes, curating the related section for a post very easy if you are using the WordPress or Drupal plugins
To do this, look for the Choose Related Posts button. In WordPress, this is above the Publish button.
In Drupal, the button's location is dependent on where your tech team puts the curation button.
When you press it, you'll see a search box that searches your own site or any sites you have set up for us to search.
Click the Add -> button to choose a story. Use the trash can icon to remove ones you have chosen before. Press Save when done.
You may edit these at any time.
