Hey everyone, I honestly am not sure how to describe what I am trying to do so I am just going to go and paste what I have and what I need to get. Previously it was being done by creating lists with the year and then mutating it onto the existing data.
What I have
| Segment1 | Segment2 | Segment3 |
| Programs | ADV | LIA |
| Programs | ADV | PRO |
What I want to get

Thanks once again in advance!
