Hi Jimbozeubuen,
I can understand the benefit of being able to add classes to only some accounts as opposed to all. However, in QuickBooks Desktop, this option is currently not available. If you'd like to see this in future updates, you can provide feedback to our Development Team by going to Help from the menu bar and select Send Feedback Online. Your recommendations are greatly appreciated. For your reference, here's additional information for setting up and using class tracking in QuickBooks Desktop.
Take care and enjoy the rest of your day!
