Bonjour, il était question de proposer des cartes miroir entre plusieurs travaux...

Cette fonctionnalité serait très appréciée, j'en suis sûr.

Hi @v_de_louvigny! Thanks for bringing your interest in this feature. Currently, Trello doesn't have the option to mirror cards (two-way), but it's something we're collecting feedback on from our users. Thanks for helping us improve Trello! 

However, you can synchronize them one way using Trello Automation. You can learn more about synchronizing your cards here: https://support.atlassian.com/trello/docs/synchronizing-cards/. I hope this helps!
