Debug Two Instances of the Same Solution Simultaneously

Is there a way to debug two separate instances of the same solution simultaneously in Rider? I have my options set up such that it opens solutions in a new window or Rider, and this allows me to open different solutions at the same time. I cannot figure out how to open the same solution multiple times. This is causing me grief because I need to debug an app that can communicate with other instances of the same app. I can run one of them from the exe and debug one from Rider, but I cannot debug both from Rider. This slows down my development iterations.
