Hi All --
Please let me know what you think of the idea I submitted as it's something i run into all the time. I am calling it Concatenate Unique, and I think it would appropriately sit in the Summarize tool
https://community.alteryx.com/t5/Alteryx-Designer-Ideas/Concatenate-Unique/idi-p/942421.
I personally run into this all of the time - so I don't believe its a far stretch to think others do as well. I know there are ways around the issue using Regex, but I feel it's common enough that it should be standard functionality.
Please let me know your thoughts or go give it a like.
Kind regards,
Seth
