Woohoo! I added that little bit of code to the personal.ini then setup 3 test columns - text, shown in tag browser; comma separated text, contains names; and Long text, like comments; then directed Relationships to populate those 3 columns. I ran a Metadata Update Only and all three columns populated with the correct data in the correct order. I even restarted Calibre and it's still in the proper order.
This seriously just saved me
days, possibly
weeks, of work.
