Display Person Number under Employee's Name on Benefits Summary Page

Summary:

Is there a way to customize the Benefits Summary Page to add the Person Number under the Employee's Name?

Content (required):

In earlier versions we used to see the Person Number with the Employee Name, but this has gone away.

I have seen a similar post about this in the Idea Lab; however, I didn't see specifically how to do this. The instructions I read appeared this needed to be done in the Sandbox, but the examples that were shown were not specific to adding/showing the Person ID, but it showed other examples.
