Hi there, @Indycals.

Let me join in this conversation and share more insights about the limitations in QuickBooks Desktop (QBDT). 

Both QuickBooks Desktop for Windows and Mac have limits on the number of names you can enter in the program. 

The total numbers you can add together (Employees, Customers, Vendors, and Other Names) is 14,500. 

If you've already reached the maximum number, the solution you've shared would be a great workaround.

For more details, you can also check out this article: Maximum Number of List Entries (List Limits and Custom Fields).

If your company file has grown too large, you can condense the transactions for a period of time you choose. This provides you an option to remove their detail and creates a consolidated journal entry for data prior to the selected date.

Let me know how else I can help you with QuickBooks by adding a comment below. I'm more than happy to lend a helping hand. Keep safe!
