Working with processing batches of tax notices that have varying numbers of pages in each document. We want to capture all the roll numbers in that column across each page of the notice into a single list of roll numbers into a "Roll Number" multi-value field. With pattern matching i can easily grab all the values on a pages into that multi-value field but I want to append all the entries from each page into the same field. I'm looking at the token accumulator in post processing but the documentation appears like it will not gather all values in a multi-value field for each page.
How can I accomplish this?
