When entering data into a constituent batch, whether you pause or type quickly, eventually (and at times often) during typing, there will be a pop up for the last name field, the primary salutation field, and the primary addressee field. I have them at the beginning of the spreadsheet to be entered but the constant pop ups are annoying and unnecessary. It would be better to not be able to tab to the next line on the spreadsheet if they are overlooked rather than random popups interrupting data entry.
