Delete link between cards with automation

[Cédric Marrouat]

Hi all, 

In my board, I have cards that are linked together (attachments).
I do this using trello fonction inside the attachments button (nothing crazy here).

But when I move a card to a new list, I manually delete this link because I no longer need these cards to be linked.

Unfortunately, I do this a lot and put a lot of time to manually delete these linked cards when a put them to my "final" list.

Is it possible to automatically delete the attachment of a card when I move them to a list ? 

I was trying to do this with butler but I didn't find a solution...

Thanks for your help

Try this. If you are just interested for a specific list. Just change the trigger.

when a card is moved into list "{*}", for each card linked in the attachments, unlink the cards
