Conditional Concatenate/ If Aggregation

How do you join a cell separated by a comma (,) if a certain condition is met. I.e if the "Record ID Cloned = Record ID (from any row in the data) => (then give me) “Record ID, Record ID Chain (Output)”. The Record ID Chain (Output) is the output im trying to create but we can have two columns if needed. See the table below. Thank you ! [image]
