Data Entry Form for Customers

I have added a dozen or so custom fields to the Customer base. It is possible to set the order they appear in the data entry form when I edit a customer record, but the result is a long form to scroll through. Many of the fields are short and could be grouped on a line making data entry much more efficient. Is there any way to customize this further, or am I stuck with just the order they occur as we move down the page?

You are stuck.
