Are you meant to add (for example what if one date had 1 in more than one row for the same column)? If not, what is the rule for combination?

The approach, nonetheless, is to build the rows in a Transformer stage, outputting only when processing the last record in each group (date). You can identify the last record in each group using Sort stages.
