Greetings! Kinda of a sneaky solution or what techs might call a "Workaround": you can enter the phone numbers "incorrectly" so that the mobile number is entered in the place for the work number or the mobile number where the home number would go, etc. Then the correct number would be first, even though the system "thinks" it's displaying the work number!
Hope this helps!
God Bless!
