I have a 1000 or so lines in my sheet. I need to update a set of contacts so I've set up a data upload but it only changes the data for the first instance of my reference column.
Example
Family Members
Flintstones Fred, Wilma, Pebbles, Barney, Betty, Bam Bam (my favourite)
Muppets Kermit, Ralf, Animal, Beaker, Swedish Chef, Fozzie
I want to upload an update that finds every instance of Family and inserts the latest list of Members. At present, using FAMILY as the unique reference means it only looks for one instance.
Suggestions on how to do comprehensive update would be appreciated.
