Update a Custom Field on all cards

[Sergio_P_]

I have added a Custom Fields Power-up on my board. One of these is a number field, and I need to reset it to 0 in all cards which are not archived every week. This is not possible with a button on the board because there is no specific action for all the cards on the board or the cards in a list. For the same reason it is also not possible to do it with a Calendar Command since there is no such specific action to go through all the cards. Of course I am looking to do it in a single action.
Is it possible to do this some other way?

Thanks in advance.

@Sergio_P_ yep there's no "for each card" structure in Butler the way that Butler Bot used to have.
