Good Morning, @mrmartin225. 

This isn't the impression I want to leave you with. I'll send feedback to our Product Developers so they can consider allowing other users rather than the Master Admin to use this feature in QuickBooks Online. We're always trying to add and improve the app's features for every customer. 

In the meantime, you can check out our QuickBooks Blog to see what's new in the product. Here's a link that may be helpful for your business in the future: Set up mileage tracking and vehicles in QuickBooks Online. 

Let me know if there's anything else I can help you with. Have a great rest of your week!
