Hi All,
I would like to ask for some guidance how do I only sequence repeated item in a list (but not all the item) in a list like the screenshot below ?
Thanks in advance everyone 
You could check for all unique items and their count with a node from the Clockwork package, then you could use a range (codeblock or normal) and then add these together
One approach would be to flatten the list, group by key using itself as the key, you can then add a ‘1…count’ sequence to the end as required, then use the ‘001,002’ portion of the string as a key to group them back to the original formatting.
Hi Hamish,
Your solution worked !, thank you very much … I really need to learn to use groupbykey
have a good day
