Is there a power up that can set card due dates based on one primary date?

 To provide more context, I am an event planner, and we will have a template board that is then duplicated for each event. We want the card due dates to be adjusted for all cards based on the event date. This means that if registration always opens 15 weeks before the event, when we enter the event date into the board, it will update the registration card with a due date that is 15 weeks before the event.

Sounds like something this one can do: https://trello.com/power-ups/6779abb0e786003b26f7763a (Batch update card fields in bulk)

Thanks, but I don't think that is exactly what we are looking for. 

I will continue to search!
