How to duplicate a card on add to list

[Jacob Hornbeck]

Just putting this out there... I don't think it is possible, but I want to ask, just in case it is.

I have a Trello board with a few different lists. One list is for task done, and the other few are different types of tasks. I want to add an automation where when I add a card to the "Done" list, that it will then duplicate the card and put it back into the list it was originally in.

As an example, let's say I have a card called "Finish homepage", when I drag it into the "Done" list, I want it to either place a duplicate card back where it came from or move the card back and place a duplicate in the "Done" list. Is this possible?

There is this variable {triggercardpreviouslistname} you can use.
