I'd like to know more about this, 1040andMore.

Are you referring to the Total only drop-down arrow in the Job Estimates vs Actual Detail report?

If yes, you're unable to choose the name in the drop-down since when you pull up the report, it'll let you choose the specific customer.

Please check the screenshot as your reference.

Feel free to get back on this thread if you need more help. Have a nice day!
