By my definition, Word 2007 was always broke. In virtually every way it was inferior to Word 2003.
Word 2010 is far superior.
Word 2013 and 2016 are both better and worse than 2010; both are superior to 2007.
Both Word 2013 and 2016 have something called a Repeating Section Content Control which would make what you are doing manually a lot easier, but would still not be automatic.
