Had to solve this differently than I might have on Desktop, this is exactly the reason why doing cloud challenges is so good!
Solved during the Australian Cloud Weekly Challenge Hour by myself, @leofrancia , Jimmy and Charlie!
This one was nice
Here is the workflow I created for a solution.
Interesting that the tile tool doesn't rank like it does in Designer. For example, I have my rows sorted in a descending order, based on a column. I select "unique value" on that column, using the tile tool. It then returns the ranks but in reverse order i.e. largest rank assigned to the first row it sees.
All the best,
BS
I might have done this slightly differently in Designer, but a simple one nonetheless.
