Dear Mark Cooperider
Good day! Thank you for posting to Microsoft Community. We are happy to help you.
According to my investigation, as well as the instructions of the official documentation, the feature you mentioned is not currently supported in Excel 2019: Excel data types: Stocks and geography - Microsoft Support
You can try Excel on the web to see if it can help you: visitthe Office portal, log in to your account and click on the Excel application
Thanks for your cooperation.
Sincerely,
Tin | Microsoft Community Moderator
