how to force a unique column


I have a column with these values (A,B,A,A,C).

I need a progressive number for each row and an output like this (A1,B1,A2,A3,C1).

How can i do that?


You can achive this by looping over the values.

works the following way:

Group Loop Start, Counter node, loop end, sorter
