Update second date automatically in Trello

[SarahH]

I am a very new user of Trello and I need to set up cards that are based on the due date of the first card I have set up.  Therefore, I would like the due date on these other cards to automatically change if I change the initial card's due date.  Does anyone have any suggestions?

Right now, due dates are unique to cards so changing this will not affect the due dates on other cards. You might want to check out the TeamGantt Power-Up which might be able to help creating dependencies between tasks: http://info.trello.com/power-ups/teamgantt
