Thanks for joining us here in the thread, @kerry914. I'll share some details about your concern along with the work around.
I understand that having the option to select both the project's name and customer name in two separate fields is what you need. Currently, the feature you want to access here in QuickBooks Online (QBO) is unavailable. The field can select the project and the customer's name in 1 row. Then once you've selected the customer's name, the project name will automatically disappear. As a workaround, you can add the name of the customer to the project itself. You also have the option to create a custom field.
I'd recommend letting our Product Development Team know about this. They'll put your suggestion into consideration for future product updates. You can click the Gear icon in the upper-right corner and select Feedback.
