Import Function: ONLY update empty fields

Import Function: ONLY update empty fields

When setting up an import from a spreadsheet to CRM, there is a checkbox "Don't update empty values for existing contacts" (see screenshot below). While I see some limited benefit from this functionality, I think there should also be an "ONLY update empty fields" checkbox because I am continually working around the fact that existing contacts may have info in fields that I do not want updated BUT if the field is empty it would be GREAT to have the imported data placed in those EMPTY fields. Could this be added to the list of possible improvements? Thank you.
