Is it possible to change the status of "Mark complete" on the front of each card via automation?

[Steve Barker]

Hi - it would be great if the check marks on the card fronts in Trello (Mark Complete) can be set/un-set in bulk using an Automation (either a button or a trigger). Is that something that can be added please?

At an individual card level you can

When a card is added to list "Done", mark the card complete

There is no action to say,

mark all cards in list "Done" to Done

There is a messy automation via a card button but involves collecting all the cards then updating. I don't recommend:

Collect all cards in list "Done" into links in checklist "Update", for each card linked from an item in checklist "Update", mark card as complete

There are a few bulk action power-ups that could fit the bill...
