Is it possible in Trello to automatically generate due dates working backwards from an event date?
So the event is 10th September and Task 1 needs to be done 30 days prior to that, Task 2, 26 days before and so on. I currently have each task on a card in a list.
I can't find anything in the automations that allows a negative date.
I'm thinking that custom fields might work but when I try to automate it, it only allows a set figure to change, so it sets the due date for everything at -30 days.
Thank you
