Hello @JWebb
Your solution should be something very similar to this one:

You can avoid the cell splitters and locate a ‘Rule Engine’ node in workflow’s ‘Node 4’ position. The code can be something like:

Append Column: ‘Combination’

NOT MISSING $ColumnValues$ => $ColumnNames$

Let me know if further guidance is needed.
