DM Logic Accounts: need to prevent summarization of identical rows

Summary:

We are duplicating transactions 1-by-1 using logic accounts and everything was working as expected, except with a recent load file that contained 5 rows which were identical. In this case, the Logic Account aggregates the 5 rows into just one - which makes sense with the default setting of Operator "NA", but this behavior is not desired for our Transaction Matching use case.

I've reviewed the documentation and wasn't able to find a setting that prevents the summarization of the 5 identical records into a single record, so that the 5 records remain individual records. Is there a way to prevent the summarization from happening?
