Can you link a path to a path?

Is it possible to link a path to another path?

I’m working with an existing learning path. A new learning path was created that addresses an important and complex topic; this new path contains several activities, which are displayed as cards. How can this new learning path be included in the original learning path to create the smoothest user experience? We currently have the topic as an activity that includes a brief description and instructions to go to a URL to complete the other learning modules and then to select the “Mark as complete” button on the activity in the original learning path. Is there a more elegant way to do that?

On the original path, I tried to see if I could import the new path, but I only see an option for “Add Activity” in the original path.

Thank you.
